Hello!
I have a signal and, with its last M values, I want to build another signal, where M is a variable input. How can I implement this in Simulink?
Details: I used a Unit Delay and a MATLAB Function and I tried not to use dynamical memory allocation (I used assert ), I got an error so I checked Variable size for my signals in Model Explorer , and now I still have an error that tells me that my signal has variable size but the upper bound is not specified. How can I set the upper bound? I already tried Limit range in Model Explorer , doesn't work.
Thanks!

Does the error point to the MATLAB Function block? If so, on the block's Ports and Data Manager, you need to select the 'Variable-size' checkbox and enter the maximum size of the signal in the 'Size' parameter.
