MATLAB: Zeros in data for gamma distribution

Question

Hi, I am working with a large weather data set. I am trying to create a histogram with a gamma distrubution. This is not possible because I have values equal to 0 on my set. Is there any way I can delete the observations that = 0 by coding?

Thanks in advance for your help

number_of_bins = 10;
histfit(rain1, 10,'gamma');
xlabel('mm');
title('station 1 jja');
