In my simulink model where i am using block "Interpreted Matlab function" and the function is:

function test = testFunc()

test = [int16(0) int16(0)]

i get error :

An error occurred while running the simulation and the simulation was terminated Caused by:

Error in 'test2/Interpreted MATLAB Function'. Evaluation of expression resulted in an invalid output. Only finite double vector or matrix outputs are supported

Edit: It crashes in second iteration

What am i doing wrong? Thanks for help

Why interpreted matlab function for a function like this? Can't you use instead Data Type Conversion block for it?

At the end of the page, you'll see Characteristics pane and there, Data Types->Double is written

Maybe your function output is not a double type data, change your output to a double type data and see if it works? I have met the same problem before and I solve it out by changing my output data to double type using "output=double(output)". Hope this is helpful.
