# calfrq

frequency response discretization

### Syntax

[frq, bnds, split] = calfrq(h, fmin, fmax)

### Arguments

- h
A siso or simo linear dynamical system, in state space, transfer function or zpk representations, in continuous or discrete time.

- fmin,fmax
real scalars (min and max frequencies in Hz)

- frq
row vector (discretization of the frequency interval)

- bnds
vector

`[Rmin Rmax Imin Imax]`

where`Rmin`

and`Rmax`

are the lower and upper bounds of the frequency response real part,`Imin`

and`Imax`

are the lower and upper bounds of the frequency response imaginary part,- split
vector of frq splitting points indexes

### Description

frequency response discretization; `frq`

is the
discretization of `[fmin,fmax]`

such that the peaks in
the frequency response are well represented.

Singularities are located between `frq(split(k)-1)`

and `frq(split(k))`

for `k>1`

.
