I have no idea what the matrix dimension problem is, since we have only one line of your code. However, the way to compare strings and string variables is to use the strcmp or strcmpi functions.
So the correct syntax for the line you posted would be:
elseif strcmpi(c, 'multi')

I came across a similar problem. Simply replace the single quotation marks with the double quotation marks, i.e. replace the line in your code with
c == "multi"
