MATLAB: Using global variable to define a Simulink block parameter

block parameterglobal variablesimulink

Hi, i guess it should have been simple but i cant find a solution since long time. I have a simulink model that has a "Matlab function" block. I have a parameters' function that i load each time automatically using simulink Callbacks=> InitFcn. I want my Matlab functin block to take its Sample time parameter defined in this init function, but it does not work.

but when i define the parameter manually in the matlab workspace, the block takes it.

any ideas !!

thanks in advance,

In the InitFcn call, does it call a M-function or M-script? I suspect this is another case of function workspace and base workspace.

Clear the base workspace using "clear", then run whatever is in the InitFcn. Then check the base worksapce, do you see the sample time parameter?

As you indicated, you need to set the sample time parameter in the MATLAB base workspace.

Use Simset. See details here. The 'DstWorkspace' property specifies the workspace in which to assign any variables defined in the model. The default is the current workspace. Change the destination workspace to 'Base'. Hope this helps!!

MATLAB: How to access variables in the model workspace from model callback functions

Model callbacks such as "InitFcn" can by default, only access the base workspace. In order to access model workspace variables, you need to do something like (within the "InitFcn" for example):

% Extract the model workspace obj
wksp = get_param('Model', 'ModelWorkspace'); 
% Extract the relevant model workspace variable
newVar = getVariable(wksp,'modelWkspVar');
