I want to call the variable "sigdata" in simulink using from workspace but I am receiving the following error message.
Error using horzcat
Dimensions of matrices being concatenated are not consistent.
time=[0:0.1:1001]';
y1 = wgn(1000,1,0);
time=[0:0.1:101]';
y1 = wgn(1011,1,0);
y2=y1';
sigdata=[time y2];

Best Answer

time=[0:0.1:101]';
y1=wgn(size(time,2),size(time,1),0);
y2=y1';
sigdata=[time y2];
