I want to compare the performance and speed of running the same script as floating-point and fixed-point. How do I simple convert the script or parts of the script into fixed-point from double?
I have tried fi(). However there seems to be a problem using it within function such as fft's. What is the best way to do this?

You can refer to the Fixed-point converter app given in the toolbox:
Furthermore, to effectively convert FFT to fixed point, you can refer to the following documentation as a starting point:
