I have a character array with values
val =
HINDALCOJAN2016FUT
INFRATELJAN2016FUT
INFRATELJAN2016FUT
NMDCJAN2016FUT
NMDCJAN2016FUT
SBINJAN2016FUT
SBINJAN2016FUT
I want to get the length of the string of each element in the character array. I know how to get the length using the for loop. Is there any efficient method other than using for loop?
After knowing the length of each string, I need to extract strings from position 1 to length of each string minus 10

f = fopen('20160427.txt');
c = textscan(f,'%s','delimiter','\n');
fclose(f);
out = cellfun(@(x)x(1:end-10),c{:},'un',0);
