I have a vector of numbers: num = [1:16]; I would like to place the character: 'B' in front of each number i that vector without using the for loop.
Are there any tricks to do this quickly?
The result should look like this:
[B1 B2 B3 B4........]
thanks.

I hope you're not trying to use EVAL to create separate variables with auto-generated names B1, B2,... That is a Notoriously Bad Thing To Do.

result = arrayfun(@(i) ['B',num2str(i)] , num , 'uni',0);

[ '[' sprintf('B%d ',1:16) ']']
