Define input and output vector/matrix

Hi guys,

I am new to use Matlab to solve functions and there is one problem that I hope you guys can help me.

The situation is, input A as a m*1 vector, like [1,2,3]; after calculation in a equation we get output B (result is a m*1 vector); then another vector input C, n*1, is involved; after input in another equation (contain both B and C) for calculation, we get result D, which should be a m*n matrix.

In this scenario, how can I define A, B, C, and finally get the result D in a matrix format?

Thanks,

It very much depends on what the ‘calculations’ are. It could require simple matrix algebra or something more involved. Two functions that would likely be helpful are bsxfun and arrayfun.

The calculations are simple, there are many coefficients involved, but in short, it is like B=k*A, A and B are the vectors I mentioned and k is the sum of all coefficients. Could you please help me out how to do it? Thanks

Is ‘k’ a scalar, vector, or matrix?

What are the sizes of all the vectors and matrices in your calculations?

In what order do you want to do them?
