How can I write a function that gives out a matrix with the specified rows and columns?

Write a function getfancyrectangle(R,C) that takes the number of rows and columns and returns a string as a character matrix, containing a "fancy" rectangle filled with alternating '@' and '#' characters.

For example:

R=2
C=3

@#@
#@#

This is obviously a homework question. As usual we will not solve it for you, such that you keep the chance to submit a solution without cheating.

Better post, what you have tried so far and ask a specific question.

This is what I have so far. However, everytime I try to run the function it says there is an error and that I don't have enough input arguments. What does this mean?

    function s = getfancyrectangle(R,C)
        % R=4; C=5;

        if mod(R,2)==0
            s = getfancyrectangle(R+1,C);
            s(end,:)= [];
        else
            s = repmat('#',R,C);
            s(1:2:end) = '@';
        end
    end

A hint:

n = 10;
x = repmat(1, 1, n);
x(2:2:n) = 2;

Your function as of the comment works nicely

    >> s = getfancyrectangle( 4, 5 )
    s =
    @#@#@
    #@#@#
    @#@#@
    #@#@#

and see function, Declare function name, inputs, and outputs
