## Calculate Model Reachability Matrix

### Description

Calculate the singular values of the reachability matrix of a model.

### Usage

        reachability(model)
        ## S3 method for class 'ARMA':
        reachability(model)
        ## S3 method for class 'SS':
        reachability(model)
        ## S3 method for class 'TSestModel':
        reachability(model)

### Arguments

`model` | An object containing TSmodel.

### Details

If all singular values are significantly different from zero the model is controllable.

### Value

The singular values of the reachability matrix.

### Examples

    if(is.R()) data("eg1.DSE.data.diff", package="dse1")
    model <- toSS(estVARXls(eg1.DSE.data.diff))
