# sparssdata

Access first-order sparse state-space model data

## Description

`[`

returns the `A`

,`B`

,`C`

,`D`

,`E`

] = sparssdata(`sys`

)`A`

, `B`

, `C`

,
`D`

, `E`

matrices of the sparse state-space model
`sys`

. If `sys`

is not a `sparss`

model,
it is first converted to `sparss`

model form.

When your system has internal delays, `sparssdata`

returns the matrices
for `pade(sys,0)`

, which involves feedback loops around the internal delays
and the model is retained in differential algebraic equation (DAE) form to preserve
sparsity. As a result, the size of matrices `A`

and
`E`

are typically larger than the order of
`sys`

.
