Hi guys I have a matrix and I want to pull a subset matrix but only with the numbers whose last digit is one. EX a= 00110, 01000, 01011, 01101. thus b= 01011, 01101

Are the entries for the first row '00110' which is to say characters? Are they [0 0 1 1 0] which is to say distinct decimal numbers? Are they 00110 decimal, which would show up as 110, decimal one hundred and ten?

a(a(:,end)=='1',:)

You said the entries were characters, and '1' will not == to 1 .
You also specifically wanted the last digit, but if your array were wider than 5 digits then a(:,5) would not be the last digit.
If your values are numeric instead of character, then a(a(:,end)==1,:)

If a is a matrix of characters, you can do:
a= ['00110'; '01000'; '01011'; '01101'];
i = strfind(a(:,end)', '1');
b = a(i,:);
