## ifrf

Frequency response function to shocks

#### Syntax

    [W,List] = ifrf(M,Freq,...)

#### Input arguments

- `M` [ model ] - Model object for which the frequency response function will be computed.

- `Freq` [ numeric ] - Vector of frequencies for which the response function will be computed.

#### Output arguments

- `W` [ numeric ] - Array with frequency responses of transition variables (in rows) to shocks (in columns).

- `List` [ cell ] - List of transition variables in rows of the `W` matrix, and list of shocks in columns of the `W` matrix.

#### Options

- `'output='` [ `'namedmat'` | `'numeric'` ] - Output matrix `W` will be either a namedmat object or a plain numeric array; if the option `'select='` is used, `'output='` is always `'namedmat'`.

- `'select='` [ char | cellstr | `Inf` ] - Return the frequency response function only for selected variables and/or selected shocks.
