I have several large discrete-time Simulink models, built from fairy simple components, with vector/matrix ops, and I would like to quantify and compare their arithmetic complexity (e.g. the number of ADD, SUB, MUL & DIV operations, and perhaps delays) per input sample. Is there an in-built analysis tool that will do this automatically for me?
Thanks,
Hugh
Not sure about built-in analysis tools, but you can use find_system and get_param to find blocks by type and their connections. If you obtain the graph of your system as some data in Matlab, you can probably use methods of circuit complexity.

There is no arithmetic tool to determine arithmetic complexity in Simulink. You have to use matlab to simulate circuits and study them.
