If you want the result to also be a string, then:

b = a(2:3);

If you want the result to be a number, then:

b = str2double(a(2:3));

[Walter Roberson]

str2double() is better than str2num(): str2num invokes eval() which is expensive and fragile for this purpose. For example if the two characters happened to be '!3' then str2num would attempt to invoke a program named "3" at the operating system level.
