casc(1)

NAME
casc - cascade realization of filter from coefficients

CALLING SEQUENCE
[cels]=casc(x,z)

PARAMETERS

x   : (4xN)-matrix where each column is a cascade element, the first two column entries being the numerator coefficients and the second two column entries being the denominator coefficients

z   : string representing the cascade variable

cels
    : resulting cascade representation

DESCRIPTION
Creates cascade realization of filter from a matrix of coefficients

EXAMPLE
--> x         =
 !   1.     2.     3.  !
 !   4.     5.     6.  !
 !   7.     8.     9.  !
 !   10.    11.    12. !
-->cels=casc(x,'z')
 cels      =
 !             2               2               2  !
 !   1 + 4z + z      2 + 5z + z      3 + 6z + z   !
