Hi all,

I have a signal vector... i would like to add some random noise, or some arbitrary peaks somewhere on the signal, or change the weight distribution of it (for example shifting the weight more on the right part or on the left part)... etc.

How can i do such modifications on my signal using Matlab? Are there functions for it... or do you have any suggestions?

Thanks a lot !
 

for gaussian noise you can use randn.
I do not really understand what you mean by adding peaks or change the weight distribution but you can always add vectors together...
