How to load matrix variables as constant on Simulink?

I am trying to load matrix variables on simulink as constant value from '.mat' file. Is it possible to load MATLAB variables on Simulink and use it as constant block value? All variables are N-d array. I found that there are several ways to load a variable on Simulink such as "From File Block" or "Input Port", but It did not work for my project.

 Accepted Answer

Load the .mat file into the Base Workspace of MATLAB, and in Simulink use the From Workspace block to enter the variable name there.

Thank you for answering! I tried "Workspace block" but it required time information. The variable which I want to import is time-invariant constant. Is it available to import constant variable without timestep?

Ah, if your Matrix is just a time-invariant constant, you can use a 'Constant' block, and as a value enter the name of your matrix variable. The From Workspace block is to read and sample a variable from the base workspace, so indeed the purpose is different.
Like here, I have the variable 'decimation' in the base workspace and I can just use it in my model through a Constant block.
Wow, It works well. Thank you!!
