Hi I have a question about calling contents of a .mat file into function. for example you save some matrices into .mat file and now you want to calling them into function.

How can do it please?

Fatema - see the load function for details on loading a mat file.

Thank you, I have done that I have loaded('test.mat')like that:

    function base=MyBase()
load('test.mat')
evalin('base','variable')
%my code

but for handling this function it is needed to load my .mat file from command window before. I want that I can handle or run my function without loading mat file from command window before that. thank you

Fatema - I don't understand what you mean by it is needed to load my .mat file from command window before. Why not assign, in your function, the result of the load to a structure as

 data = load('test.mat');

And, what is the purpose of the evalin call?

You can extract the variable which you want from the model workspace doing the following in a Matlab Function block:

coder.extrinsic('get_param','getVariable');

mdlWks = get_param('your_model.slx','ModelWorkspace');

variable= getVariable(mdlWks,'variable_name');
