does anyone know, is there code for finding peaks in a matrix that have noise? (because of this noise i cant use findpeaks command in matlab) the noise has so small amplitude in compared with amplitude of main wave. thanks

If you have noise in the data, you need to filter it first. See:

You don't. That is the parameter to specify your designed filter. See the example in the doc.

You might try one of the FEX submissions, e.g. PeakFinder by Nate Yoder:

use xlsread() to read the data into MATLAB workspace first, then apply filter.

Can you explain why you cannot use findpeaks? I think you can specify MinPeakHeight to avoid false alarm from the noise.

Sometimes identifying the noise would be a good start. Try Allan Variance method.
