Scilab Function

lindquist - Lindquist's algorithm

### Calling Sequence

  `[P,R,T]=lindquist(n,H,F,G,R0)`

### Parameters

- `n` : number of iterations.
- `H, F, G` : estimated triple from the covariance sequence of `y`.
- `R0` : E(yk*yk')
- `P` : solution of the Riccati equation after n iterations.
- `R, T` : gain matrices of the filter.

### Description

computes iteratively the minimal solution of the algebraic Riccati equation and gives the matrices `R` and `T` of the filter model, by the Lindquist's algorithm.
