Unable to perform assignment because the left and right sides have a different number of elements.

I am trying to build an array for calculating wind-gust factor ratios for different averaged time intervals and I am running into the error as described in the title of this post.

Script:

numdata = length(wspd);

numgusts = floor(numdata/600);

g3_60 = zeros(numgusts,1);

g3_600 = zeros(numgusts,1);

g60_600 = zeros(numgusts,1);

for qq = 1:numgusts

sp = 1 + (qq-1)*600;

ep = qq*600

g3_60(qq) = max(wspd3(ep:sp)) / max(wavg1(ep:sp));

g3_600(qq) = max(wspd3(ep:sp)) / W10(ep);

g60_600(qq) = max(wavg1(ep:sp)) / W10(ep);

end

For context, wspd3 is 3-sec averages or 3 data points for a file with data every second, wavg1 is 1 min data or 60 points, and W10 is 10 min data or 600 points. numdata = 43201 and numgusts = 72

I would appreciate any advice/answers! Thank you so much for your time!

Your array indexes are backwards, so the RHS is zero-length

g3_60(qq) = max(wspd3(sp:ep)) / max(wavg1(sp:ep));

I don't know which index you intend to use in the indexing of W10.
