# Extract "true" model-implied covariance matrix for several points in time

### Description

`covmat`

extracts the model-implied (time-varying) covariance matrix
from an `fsvsim`

object.

### Usage

1 2 |

### Arguments

`x` |
Object of class |

`these` |
Vector indicating which points in time should be extracted, defaults to all. |

`...` |
Ignored. |

### Value

Array of dimension `m`

times `m`

times
`length(these)`

, containing the model-implied covariance matrix.

### Note

Currently crudely implemented as an R loop over all time points, may be slow.
