Hi,

I am having issues concatenating 3 outputs (1x1, 3x1, and 3x3) that are the inputs to a matlab function SIMULINK block. Is there a way I can concatenate or use a different approach to merge those 3 ouputs into one signal so I can use them in my matlab function block?

I have attached a picture showing the basic setup and also the error message.

Thanks!

If you are trying to concatenate a 1x1, 3x1 and 3x3 input, how do you expect the output to look like? It's not possible...

I think you are more looking for a Bus Creator. With a bus you can 'merge' different signals of different sizes and data types. A Bus is essentially a struct from C code.
