Is there an easy way to compare the contents of 2 subsystems in MatLab? I want to take one subsystem and check it against another to ensure the contents of both are the same. I didn't want to try to create a loop that'll take all the block from the subsystems and loop through them checking each parameter of each block to make sure all the logical operator are the same.

I don't know what you mean with "subsystem", but if you have two variables with any kind of data (no matter if it's a struct or a cell or a numerical array) and you want to check for equality, use isequal(var1,var2).

I didn't work with Simulink so far, so I cannot tell you if this works there as well. In Matlab you would use isequal.

As Simulink wasn't mentioned anywhere, I'll add this as the product here.

I tried to use isequal, but it only works for the blocks in the subsystems, it doesn't compare the parameters. If I have to do it by hand, I'll have to use isequal on all the blocks parameters as well.
