[Scilab-users] vector product (hyper)matrix and vector

[Adelson]

Hello,

How to obtain the product of a one dimensional array and a hypermatrix in a
vector way?

I mean, an array a(1:N) times a hypermatrix H(1:M,1:N,1:P,....), for all
m,p,q,... indices:

for m=1:M
  for p=1:P
    for q=.....
       ....
           R(m,:,p,q,....) =H(m,:,p,q,...) .* a(:);
       ....
    end
  end
end

in a vectorized form?

As an example, in FORTRAN one could simply write in a vectorized form,

FORALL(m=1:M,p=1:P,q=...,...); R(m,:,p,q,...)=H(m,:,p,q,....)*a(:);

And, it seems that in MATLAB one could do something similar using the comand
DOT.

Thanks
