I am trying to get the length of an array, and exclude NaN values. At the end of the column there are some NaNs. How can I ignore those?
I tried:
length(thisS(:,11))
But this includes the Nans
When I try:
length(thisS(~isnan((:,11)))
I get:
length(thisS(~isnan((:,11)))
↑
Error: Invalid use of operator.

num_no_nans = sum( ~isnan(thisS(:,11)) )
