I have a (130,93) matrix and I need to know how many times the numbers in each column goes above a certain value, this value stays the same for each column. Please can someone help me out?

‘... this value stays the same for each column.’
Wouldn’t you just need to count one column then?

I'm not positive re: the comment about value being same for each column, either, but the given the prhasing I'm guessing it's referring to the threshold. If so, solution is simply
s=sum(x>threshold);
If the threshold were by column instead, then
s=sum(bsxfun(@gt,x,threshold));
where threshold is a row vector of length size(x,2)
