MATLAB: Is it possible to dynamically set the “FIR coefficients” of an “Overlap-Add FFT Filter” block with a signal in Signal Processing Blockset 6.5 (R2007a)

Question

I have a model which I need to use with xPC Target. Since there is no model workspace where I can store the coefficients, I want to dynamically set the "FIR coefficients" of an "Overlap-Add FFT Filter" block with a signal.

Answer 1

The ability to dynamically set the "FIR coefficients" for "Overlap-Add FFT Filter" block is not available in Signal Processing Blockset.

To work around this issue, you need to write your own S-function implementation of the block.
