Hi,

how can I create a for loop between in this statement

CM4_380 = spec_data(spec_data.wavelength>380 & spec_data.wavelength<381,:);

so it for loops between 380:780? Basically, to make this:

CM4_381 = spec_data(spec_data.wavelength>381 & spec_data.wavelength<382,:);

CM4_382 = spec_data(spec_data.wavelength>382 & spec_data.wavelength<383,:);

CM4_383 = spec_data(spec_data.wavelength>383 & spec_data.wavelength<384,:);

etc. Plus I need to save each of those tables.

Thank you for your help!

I would use a cell array, not variable names that also encode an index:

for ic = 380:780
    CM4{ic} = spec_data(spec_data.wavelength>ic & spec_data.wavelength<(ic+1),:);
end

I would suggest

for ic = 380:780
    CM4{ic-380+1} = spec_data(spec_data.wavelength>ic & spec_data.wavelength<(ic+1),:);
end

unless you have a use for CM4{1} to CM4{379}

I does work, thank you!
