Let's say I have a matrix of the form:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/236831/image.png)
Starting from this matrix, I would like to calculate a new matrix, in a time efficient way:

The algorithm, which I am looking for, should also work for a matrix of the form:

Does someone know how this algorithm could look like?

Assuming Astart is n-by-2 array, straight-forward way to calculate Aend would be:
Aend = [Astart(:,1).^2 Astart(:,1).*Astart(:,2) Astart(:,2).*Astart(:,1) Astart(:,2).^2];
But it's not clear for me what Aend looks like when Astart is n-by-m array.
Could you explain more detail on this?

Aend = reshape(Abegin.*permute(Abegin,[1,3,2]),size(Abegin,1),[]);
