Obviously homework...show your work to date and where, specifically, you got stuck on a Matlab-related question.
Of course, you start with the definition of what matrix multiplication is...

Here you go
function result = mult(a, b)
[r1, c1] = size(a);
[r2, c2] = size(b);
if( c1 == r2)
result = zeros(r1, c2);
for i = 1: r1
for j =1:c2
for k = 1:r2
result(i,j) = result(i,j) + a(i,k) * b(k,j);
end
end
end
else
result = [];
end
disp(result)
end

Providing a complete solution to a homework problem is totally not recommended in this forum.
