WebNote. The fircls function always uses an even filter order for configurations with a passband at the Nyquist frequency (that is, highpass and bandstop filters). This is because for odd orders, the frequency response at the Nyquist frequency is necessarily 0. If you specify an odd-valued n, fircls increments it by 1.

But I want to constrain h to be of the form ejθ ( n), i.e., a complex valued filter with a magnitude of 1 on every filter tap. This may be an impossible constraint, so an alternative might be minimizing the peak-to-RMS ratio of the tap ... WebImage Recovery: Part 1.
