The original source Matlab m-files that were used to generate these P-files should be used in Octave instead.

I tried it with non-square matrices just now and the original code still seemed to produce the right answer. Matlab P-files files with a. Matlab classdef object oriented programming is only partially supported, see classdef for details. How does Octave solve linear systems? Is there anything I should watch out for?

Plot hangs and makes the GUI unresponsive[ edit ] If the Qt graphics toolkit is used and "plot" is used for the first time, the fontconfig scanner searches the font directory to build a font cache. Differences in core syntax[ edit ] There are a few core Matlab syntaxes that are not accepted by Octave, these being Some limitations on the use of function handles.

For example the sprandn function can not force a particular condition number for the matrix like Matlab can.

If you refer to the latest Mercurial revision, please specify the changeset ID not the revision number, e. All arrays are stored in a specific way, with element indexes having a specific order.

It is best to avoid creating your own scripts or functions that have the same name as an Octave function.

Therefore I use the "number of columns of original matrix a" instead of "number of rows of transposed matrix a" as a parameter for the reshape function. The following example helps to find the function to calculate correlation coefficient in a matrix: This can take up to 3min on slow CPUs.

Octave has limited support for nested functions since version 3. Because this infinite repetition cannot be represented exactly with a finite number of digits, rounding errors occur for values that appear to be exact in decimal but are in fact approximations in binary, such as for example how 0.

In binary, the representation to one tenth is where the bar indicates that it repeats infinitely like how in decimal.

Furthermore, Octave adds a few syntactical extensions to Matlab that might cause some issues when exchanging files between Matlab and Octave users. Octave has a not fully functional JIT compiler. There are still a number of differences between Octave and Matlab, however in general differences between the two are considered as bugs.

Some limitations of variable argument lists on the LHS of an expression, though the most common types are accepted. The latest stable version is 4. This compiler allows the acceleration of for-loops in Matlab to almost native performance with certain restrictions.

See Error message about invalid call to script or invalid use of script in index expression[ edit ] If Octave shows an error message about invalid call to scriptGeneral [] What is Octave? [GNU Octave is a high-level interpreted language, primarily intended for numerical computations.

It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments.

I f you have two matrices, arrays or vectors that you want to interleave row by row or column by column in MATLAB, you can accomplish this with a reshape command.

This tutorial shows how to do this. Since vectors are just one-dimensional matrices, this technique will also work for them.
