Abstract: Matrix multiplication plays very important role in many scientific disciplines because of fact that it is considered as the main tool for many other computations in different areas, like ...

If \(A\) is a \(3\times 3\) matrix then we can apply a linear transformation to each rgb vector via matrix multiplication, where \([r,g,b]\) are the original values ...

We use matrices throughout multiple field of mathematics, but we seldom quite "see" what changes these matrices make. A matrix cannot have 0 as its determinant. But we can't really tell the reason ...

Enter the 2x2 matrix \(A = \begin{pmatrix} a & b\\ c & d \end{pmatrix}\). The canvas at right shows how the transformation maps the plane. <label>a (row 1, col 1 ...

The matrix M is based on the Pseudo-Hadamard Transform (PHT) in the original SAFER family of ciphers. The matrix M can be realized as a series of 2-PHT butterflies and Armenian Shuffles ( a kind of ...
