MATLAB: Vectorization: matrix array multiplication element wise one by one

multvectorization

Vectorization without loop:

I have a matrix:

R = [0 -1;1 0];
array = [1 2 3 3646 68 534 342 1 2 3];

how can I obtain another array

array2 = [1*R 2*R 3*R 3646*R 68*R ....];

array2 = kron(array, R)

Try this:

AB = reshape([a, B]', 3, [])' % Interleave arrays.

One element of an array can contain one element only. This is the definition of "element".

Perhaps you are looking for a cell:

A{1} = [1 3 5];
A{2} = [5 8 11];
B{1} = [1, 3, 5; 5, 8, 11];

These basics are explained exhaustively in the "Getting Started" chapters of the documentation.
