# Generated Code

The following is matlab code generated by the CellML API from this CellML file. (Back to language selection)

The raw code is available.

% This is the "main function".  In Matlab, things work best if you rename this function to match the filename.

% Used later when setting a global variable with the number of algebraic variables.
% Note: This is not the "main method".
