Hi all! I need your help please!
my data are 3033 lines and 2005 columns. I want to find the mean for all columns separately but the step in lines is different. For example, i want to find the mean for the first 167 lines, then from 168 to 294, 295 to 428 and so on. what code can i write?
Thank you!

You can write a=mean(M,2) - this will find mean of matrix M along each column. And then take only values you need. For 3033*2005 this is ok.

ok, so you create vector containing number of lines you want to take: a=[1:167,168...].
If you want to take into account only this lines for all columns, you can make new matrix: N=M(a,:). The new matrix contains only lines you need. And use mean.
