myfolderinfo = dir('some_random_folder') ;
N = length(myfolderinfo) ;
for i = 3:N
thisfile = myfolderinfo(i).name
some_random_folder contains text files with names 5_5.txt,6_6.txt...50_50txt,50_51.txt
now i want to assign the value after underscore to a variable m. such as for file 5_5.txt then m=5 and for file 50_51.txt then m=51
how can i assign those values to m
