## zerodb

Create model-specific zero-deviation database

#### Syntax

    [D,IsDev] = zerodb(M,Range)
    [D,IsDev] = zerodb(M,Range,NCol)

#### Input arguments

- `M` [ model ] - Model object for which the zero database will be created.

- `Range` [ numeric ] - Intended simulation range; the zero database will be created on a range that also automatically includes all the necessary lags.

- `NCol` [ numeric ] - Number of columns for each variable; the input argument `NCol` can be only used on models with one parameterisation.

#### Output arguments

- `D` [ struct ] - Database with a tseries object filled with zeros for each linearised variable, a tseries object filled with ones for each log-linearised variables, and a scalar or vector of the currently assigned values for each model parameter.

- `IsDev` [ `true` ] - The second output argument is always `true`, and can be used to set the option `'deviation='` in `model/simulate`.
