Syntax

gpz = CombineSlices (gpz1,gpz2)
gpz = CombineSlices (gpzCell)

Description

gpz = CombineSlices (gpz1,gpz2) concatenates gpz1 and gpz2 into a single 3-D GPZ matrix. If necessary, the function pad the third dimension with zeros.

gpz = CombineSlices (gpzCell) concatenates and zero-pads together in the third dimension the 2-D GPZ matrices contained in the cell array gpzCell.

Create a GPZ matrix from a uniform number of poles and zeros.

G = [-3;-4;-5;-6];
P = [-15321428571 -13848214285;...
    -15600000000 -14100000000;...
    -15878571428 -14351785714;...
    -16157142857 -14603571428];
Z = [-5574642857;-4960100000;-4435821428;-3981285714];

gpz1 = serdes.CTLE.GainPoleZeroToGPZ(G,P,Z);

Create a second GPZ matrix from a varying number of poles.

G = [0;-1;-2];
P = {[-23771428571,-13092857142];...
    [-17603571428,-13344642857];...
    [-17935714285,-13596428571,-15321428571]};
Z = {-10492857142;-7914982142;-6845464285};
gpz2 = serdes.CTLE.GainPoleZeroToGPZ(G,P,Z);

Combine the two matrices into a 3D GPZ matrix.
