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

This block computes the square root of each element of the input
matrix. It support double and complex data types ( **Datatype**
parameter).



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,-2] / type 1**
+ **regular outputs:** **- port 1 : size [-1,-2] / 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_sqrt
