How can I Repeat Signal builder output

Hi,

I want to repeat a signal builder output,

I tried to use repeat sequence it's not working, then

I have moved the data to workspace to repeat the sequence

When i am using repmat to loop, output has same time and data which is repeating,

when i am plotting, I am observing the same curve one on top of the other.

I want to repeat the same curve with time interval between two graphs as 1500.

Presently i am using

Input_a = [out.channels.Time; out.channels.Time+1500; out.channels.Time+3000; out.channels.Time+4500];

Input_b = repmat( out.channels.Data,4,1);

Is there any better way to deal this.

Thanks in advance.
