Dot Matrix

A set of blocks for manipulating 3x3 and 4x4 matrices. In versions of Simulink prior to R12, matrices were handled in row-major form, thus the need for special blocks to handle matrices. Although Simulink can now handle arrays as signals, some users may still find the row-major approach...

This short tutorial illustrates basic numerical matrix computation in C. I encourage any comments from expirienced mex programmers for style improvement.This is a nice little function to demonstrate how you can interface MATLAB and C style matricies. There is some example code included showing...

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must...

DISTMATLATLON Computes distance matrix between list of coords in X and Y D = DISTMATLATLON(X,Y) for matrices X and Y, with columns [Lat Lon], returns the distance matrix where the (i,j)th entry is the distance between the i'th and j'th row of X and Y respectively. X and Y must have columns in the...

Matrix decomposition using, e.g. the Cholesky decomposition requires the correlation matrix to be positive definite. That is, the eigenvalues must all be positive. In finance, this is rarely the case, and one often observes negative eigenvalues, or zero eigenvalues. These two functions do...
