Re: cell array dimensions do not match

Thanks, but that didnt quite work either. With those changes I got the error
??? Error using ==> rmfield at 21
FIELDNAMES must be a string or a cell array of strings.

Error in ==> remover at 33
deltaT = rmfield(data, toremove)

I resolved it by modifying my code to remove the entires in the same for loop that combined the field numbers with the field name instead of trying to make a list.

if rmvr == 1
for g = listremove
field = [stem,int2str(g)] % combining field numbers that contain no data with the stem they are named.
data = rmfield(data, field) % removing the fields from data as their field names are made
end
end

deltaT = data;

save(File, 'deltaT')

clear all
