Set difference of two sets of positive integers (much faster than built-in setdiff) which is great if you have to call it million times in a loop.

This is an eye candy screensaver, projected with aim to make your time of the rest colourful and absolutely positive, more saturated and brighter. With your favourite music you will dip into the wonderful world of the feelings and sensations, thoughts and enjoyments. And all of these only for one...

The set of vectors is passed like column vectors of a matrix.This algorithm take advantage of the matrix form using sub matrix (more vectors at the same time).I've tested it with a random 1000x1000 matrix (so 1000 vectors 1000x1) giving a result in 7.4863 sec (mean value on 5 executions... best...

In statistics, sequential analysis or sequential hypothesis testing is statistical analysis where the sample size is not fixed in advance. Instead data is evaluated as it is collected, and further sampling is stopped in accordance with a pre-defined stopping rule as soon as significant results...

We can exploit the symmetry of a real, positive definite, symmetric matrix by using the Cholesky decomposition to compute the inverse.The built-in MATLAB inv function uses LU decomposition which requires extra pivots and operations. Rarely does one actually need to compute the inverse of a matrix...

This script is capable of solving a convex quadratic programming problem by Wolf's method. For the convergence of the algorithm it is necessary that either Hessian of the objective function be positive definite or positive semidefinite Hessian with linear term zero. For theory of Wolf method and...

divisor(n) : row vector of all distinct divisors of a positive integer N, including 1 and N.Remark: This function uses the default factor() routine in Matlab and hence is limited to input values up to 2^32. However if factor() routine does get updated for larger integers, this function will still...
