# MATLAB: Operation on structure fields with common part of the field name

charfieldsMATLABstringsstructures

Hi, I have succesfully imported several mat files into a structure with fields names beginning either by "DUT" or "REF". Now I need to divide all the fileds beginning by "DUT" to the corresponding one beginning by "REF", for example, I want to compute DUT_2/REF_2, DUT_4/REF_4 etc…

• S.DUT_2 = 2;S.REF_2 = 3;S.DUT_4 = 4;S.REF_4 = 5;C = fieldnames(S);U = unique(regexp(C,'\d+\$','once','match'))F = @(n)S.(['DUT_',n]) ./ S.(['REF_',n]);Z = cellfun(F,U)
U =     '2'    '4'Z =      0.66667          0.8
