Dear all,

For a transformation operation, I needed to compute A*(R^{-1}) where A is a rectangular matrix. A has m rows, which is much larger than the column size, n. In general, the column size is between 2 and 10 and R is an upper triangular square matrix of size n.

A is meant to be a block of iteration vectors in my code. However, I have to do the inversion from right, an operation that is possible in MATLAB like 'A/R', is there way to achieve this directly or should I use the inverse of R which is less likely I suppose?

Could you please direct me on this matter?

Best regards,

Umut
