In MATLAB I want to achieve the following in one expression,

C = A * B;

C = C(:, 2:end);

Naturally it'd be something like

C = (A * B)(:, 2:end);

However that gives me an invalid expression error. How do I do this properly?

Strange as it may seem, try this

C= A * B(:, 2:end)

Terser is not always better, especially when things start to become confusing and ambiguous

Thanks. Interesting. This is actually a different method but does produce the correct solution.
