Description
~~~~~~~~~~~

The MATINV block outputs the inverse of a square input matrix
calculated by using the LU factorization. A warning message is printed
if the input is badly scaled or nearly singular.

The equivalent function of this block in Scilab is `inv`_.





Dialog box
~~~~~~~~~~






+ **Datatype(1=real double 2=Complex)** It indicates the type of the
  output. It support only the two types double (1) and complex (2). If
  we input another entry in this label xcos will print the message
  "Datatype is not supported". Properties : Type 'vec' of size 1.




Default properties
~~~~~~~~~~~~~~~~~~


+ **always active:** no
+ **direct-feedthrough:** yes
+ **zero-crossing:** no
+ **mode:** no
+ **regular inputs:** **- port 1 : size [-1,-1] / type 1**
+ **regular outputs:** **- port 1 : size [-1,-1] / type 1**
+ **number/sizes of activation inputs:** 0
+ **number/sizes of activation outputs:** 0
+ **continuous-time state:** no
+ **discrete-time state:** no
+ **object discrete-time state:** no
+ **name of computational function:** mat_inv
