Using such a complex environment can prove daunting at first, but this Cheat Sheet can help: Get to know common matlab commands; become familiar with common operators and precedence; and learn to recognize line plot styles. Common matlab commands, the following table contains a listing of commands that you use relatively often in matlab. You wont find every command listed — that would require a book in itself. However, these commands are usually used several times each session. Command, purpose cla, clears the current plot clc, clears the command window clear variable name removes a specific variable from the workspace window (as specified by variable name ) clear all. Removes all of the variables from the workspace window close figure name closes a specific figure (as specified by figure name ) close all, closes all of the current figures diary filename specifies the name of the file to use for the diary feature diary. Removes extraneous spaces from the command window gca, obtains a handle to the current axes gcf, obtains a handle to the current figure gco, obtains a handle to the current object get( handle, property ) Obtains the property found in the object pointed.

Strread and textscan in Octave.4.0 are not fully compatible with their implementations in matlab 2009b (and probably later versions as well). For instance, reviews the n-1 option (repeat reading format until end of string) is not implemented in Octave.4.0. Using a value of na positive integer (read format N times) summary does work the same as in matlab. Textscan function is not included in Octave versions prior.4.0. For the linprog function, matlab is more permissive by allowing the "a" and "b" inputs to be either row or column vectors. Octave requires that they be column vectors. In Octave, one can specify data labels (or legends) with the plot function, while in matlab, one can only use the legend function. Octave: plot(x, y, label matlab/Octave: plot(x, y legend label The error(msg) function in matlab is a no-op if the message is empty.
If something (like netlab) needs a function named fcnchk, create a file named fcnchk. M with the contents shown below and put it where Octave can find it: function ffcnchk(x, n) f x; end The main difference used to be the lack of gui for Octave. With version.0 Octave has a gui as its default interface. Notes about specific functions edit for "dbstep, in" use "dbstep for "dbstep use "dbnext" For "eig(a,b use "qz(a,b fputs function is not available in matlab. Strftime function is not available in matlab. Time function is not available in matlab. As.2.1, Octave does not print outputs to the console until it has completed all waiting commands, unlike matlab. This behavior is controlled by the boolean variable page_output_immediately (default: 0 and it is not ameliorated in -traditional.

Small differences exist - an example is gre c2d. Here are the two formats for the bilinear transformation with an analog model C: * discrete c2d(C,0.5 tustin matlab * discrete c2d(C,0.5 bi gnu octave some other differences edit matlab uses the percent sign to begin a comment. Octave uses both the hash symbol and the percent sign interchangeably.market
For exponentiation, Octave can use or matlab requires. For string delimiters, Octave can use ' or matlab requires '. To end blocks, Octave can use end or specify the block with endif, endfor,.; matlab requires end. Octave supports C-style hexadecimal notation (e.g. "0xF0 matlab requires the hex2dec function (e.g.
System touch emptyfile a load emptyfile matlab r2011b : a octave.2.0 : error: load: unable to determine file format of 'emptyfile' fprintf and printf edit Octave supports both printf and fprintf as a command for printing to the screen. Matlab requires fprintf: foo 5; printf my result is: dn foo) Prints to stdout. Octave only fprintf covers writing both to the screen and to a file by omitting the optional file-handle argument: foo 5; fprintf my result is: dn foo) Prints to stdout. Octave and matlab whitespace edit matlab does not allow whitespace before the transpose operator but Octave does (it is just an operator like others). 0 1' works in matlab and Octave 0 1 ' works only in Octave line continuation edit matlab always requires. 2) while Octave also supports rand (1, 2) Logical operator not edit Octave allows users to use both and!
The first is for matlab compatibility, while! Will be more familiar to C/java/etc programmers. If you use the latter, however, you'll be writing code that matlab will not accept: For not-equal comparison, Octave can use both or '!'. Gnu octave control Package edit both matlab and Octave have toolboxes intended to control system design. In Octave, the toolbox is called the Octave control Package. The package can be downloaded, compiled and installed with the command pkg install control from the Octave prompt. Users of Debian and its derivatives can install it by installing the package "octave-control if it is not installed by default.

String" syntax calls a shell with command string in matlab. Octave does not recognize! As system call, since it biography is used in logical operations. Always use 'system (string for compatibility. If you really miss the one-character shortcut, for convenience on the command line you can create a similar shortcut by defining the following in your '. Octaverc' file: function S(a system(a end, now "s string" will evaluate the string in the shell. Attempting to load empty files edit matlab lets you load empty files, octave does not.

M load startup. M like matlab endif 'abc abc' edit 'abc abc' is allowed in Octave; matlab returns? In Octave the system result will be a 2 by 4 matrix. Calling Shells edit the "!
and above. Nargin returns the number of input arguments of a function. Matlab (R2011b) will not allow the following; Octave will. Function myfun testfun(c) if (nargin 1) nargin 2; else nargin 3 end startup. M edit, matlab will execute a file named 'startup. M' in the directory it was called from on the command line. Old versions of Octave do not. Starting with Octave.2.0 it behaves the same as Matlab. For older versions of Octave, it will execute a file named '.
For example, octave supports the use summary of both single and double"s. Matlab only supports single"s, which means parsing errors will occur if you try to use double"s (e.g. In an Octave script when run on matlab). Octave and matlab users who must collaborate with each other need to take note of these issues and program accordingly. Note: Octave can be run in "traditional mode" (by including the -traditional flag when starting Octave) which makes it give an error when certain Octave-only syntax is used. This chapter documents instances where matlab's parser will fail to run code that will run in Octave, and instances where Octave's parser will fail to run code that will run in matlab. This page also contains notes on differences between things that are different between Octave (in traditional mode) and matlab. Contents, c-Style autoincrement and Assignment operators edit, octave supports C-style autoincrement and assignment operators: i; i; i1; etc.

From wikibooks, open books for an open world matlab programming, jump to navigation, jump to search, octave has summary been mainly built with matlab compatibility in mind. It has a lot of features in common with matlab: Matrices as fundamental data type. Built-in support for complex numbers. Powerful built-in math functions and extensive function libraries. Extensibility in the form of user-defined functions. Some of the differences that do exist between Octave and matlab can be worked around using "user preference variables.". Gnu octave is mostly compatible with matlab. However, Octave's parser allows some (often very useful) syntax that matlab's does not, so programs written for Octave might not run in matlab.
