For complex values, you must be careful with the spaces). However, FreeMat will attempt to make sense of the entries if the comma is missing (e.g., a space separated file will also parse correctly). Each entry in the file should be separated from other entries by a comma. The file can contain only numeric values. Which attempts to read the entire CSV file into array x. The first syntax for csvread is x = csvread('filename') Check your naming conventions if function files are there but still things aren’t working.The csvread function reads a text file containing comma separated values (CSV), and returns the resulting numeric matrix (2D). The file name must match what you type to call the function exactly and is case-sensitive too i.e., Comb(3,7) != comb(3,7). When you save the function, you need to give the file the same name as the function (except with ‘.m’ appended). Also check that the directory where the files are stored is in the path set by the path tool (Tools→Path Tool). Double-check that you typed the function name correctly. This means that FreeMat cannot find the function. The most common errors when trying to use functions is: Let us do a couple of simple tests on your new functions: Just as we did earlier, save the file to a directory within the working path.

The code for it is as follows:įunction return_value=perm(n,r) The permutation function is similar to the combination function. This lets FreeMat know that it is a usable script. When you save the file, put a ‘.m’ extension on it. To save the function, either select File→ Save or click ‘Save’ icon. Select Tools→Path Tool and check that the directory where the function will be stored is part of the path. To make it a function that FreeMat can use, store the file in a folder that is part of the FreeMat path. When the editor window opens up after typing ‘edit,’ enter the following combination function:įunction return_value=comb(n,r) In FreeMat, a function is a script that starts with word ‘function’ and uses the following syntax:įunction return_value = To open the FreeMat editor, first run FreeMat and then, from the command line, type in the word ‘edit’ (without the quotes). FreeMat also comes with a built-in editor for this purpose (see fig 1). In order to create functions, you can use Notepad (Windows) or vi or gedit (Linux). Here is a short tutorial to create combination and permutation functions for FreeMat, from the FreeMat project home page at.

It also features codeless interface to external C, C++ and Fortran code, parallel-distributed algorithm development (via MPI), and some extended volume and 3D visualisation capabilities.
