This function generate random variables distributed according to a truncated normal distribution (or, by a translation, to a normal distribution with positive support). This kind of problem is especially interesting for generating variables with MCMC methods.We use a mixed accept-reject... Platforms: Matlab

This is a very user friendly Gram Schmidth Algorithm implemented in MATLAB.I have already submited a file of the same algo,bt this one is bit more flexible than previous.Hope u will find it useful. Platforms: Matlab

Intersection of two sets of positive integers (works much faster than built-in intersect) Platforms: Matlab

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. Platforms: Matlab

This file : eig_svd_herm_unit_pos_def_2.m is a modified (improved) version of my previous file. The main correction has been to include issparse() instead of class() to identify a Sparse Matrix. This change is essential for R13.The file eig_svd_herm_unit_pos_def_2.m and it's companion files... Platforms: Matlab

For fixed integers a and b with D = a^2 + 4*b positive, the sequence U_n = GeneralizedFibonacci(n,a,b) satisfies the recurrence U_n = a U_{n-1} + b U_{n-2} with initial conditions U_0 = 0 and U_1 = 1. If a=b=1, this is the Fibonacci sequence. Platforms: Matlab

ORTHA Orthonormalization Relative to matrix AQ=ortha(A,X)Q=ortha('Afunc',X)computes an orthonormal basis Q for the range of X, relative to the scalar product using a positive definite and selfadjoint matrix A. That is, Q'*A*Q = I, the columns of Q span the same space as columns of X, and... Platforms: Matlab

The function performs a nonlinear, constrained optimization to find a positive semi-definite matrix that is closest (2-norm) to a symmetric matrix that is not positive semi-definite which the user provides to the function. The optimization is subject to the constraint that the output matrix'... Platforms: Matlab

Given an arbitrary basis {u1,u2,u3,...un} for an n-dimensional inner product spaceV, the Gram-Schmidt algorithm constructs an orthogonal basis {v1,v2,v3,... vn}for V. Platforms: Matlab
