Re: Multiplying Elements of arrays: Inner product


Thanks to all of you who suggested me ideas.

Yes, its easy to directly calculate the dot product of two matrices cd and ab as, ef = cd.ab (symbols as defined in my question). This question is a simplification of my original problem.

The reason I wanted to do this because I had to calculate only the product of certain section of a matrix cd with corresponding elements of column vector or another matrix.

I am also thinking of using direct multiplication of entire matrices cd and ab as such and then extracting the values of appropriate location to some dummy matrix. But if I make my previous procedure to work, I will understand better about the usage of double square closed brackets.

Thanks,
