I have a Matlab Function Block that slows down my SImulink simulation. Is there a way to execute the Matlab Function Block every X seconds so my simulation will run faster? It is unnecessary to run the Matlab Function Block every time iteration.

Hi Andrew,

you can achieve this by assigning a sample time: right click on the block, choose "Block Parameters (Subsystem)", and set the Sample Time to 1.

Thanks a lot... I searched the Internet for a long time to find this solution.

maybe this works for all other block in simulink, I was working with 'Matlab function block' • I noticed that when my sample time for the 'Matlab function block' was made more than my simulation time... I got exactly one output from the 'Matlab function block'

For some reason, this was what I wanted all along.
