frmag — magnitude of FIR and IIR filters
[xm,fr]=frmag(num[,den],npts)
| npts | : integer (number of points in frequency response) |
| xm | : mvector of magnitude of frequency response at the points fr |
| fr | : points in the frequency domain where magnitude is evaluated |
| num | : if den is omitted vector coefficients/polynomial/rational polynomial of filter |
| num | : if den is given vector coefficients/polynomial of filter numerator |
| den | : vector coefficients/polynomial of filter denominator |
calculates the magnitude of the frequency responses of FIR and IIR filters. The filter description can be one or two vectors of coefficients, one or two polynomials, or a rational polynomial.
