Error using horzcat. Dimensions of matrices being concatenated are not consistent.

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];

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

This will work just as well btw:

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