Trigonometric Identities
This above Fractal code generates a small fractal mound in using the basic trigonometric operations. This involves a basic logic of an exponential surface that modifies the vector along the XY plane while the modifying function modifies the surface to yield a 3D likesurface as can be expected...

Used to perform B*M or M*B with B a block diagonal matrix, B is stored as a cell array (call it C) with each element a matrix as a block of B, such that B = blkdiag(C{:}).This speeds up the multiplication when B is large and also allows the operation to take place when B could not fit in the...
