PCG Preconditioned Conjugate Gradients Method is a replacement of the standard built-in PCG code. Two new options are implemented: 'flex' and 'null'. The 'flex' option changes the standard PCG algorithm into the flexible one. It allows using sophisticated preconditioning, not limited to the... Platforms: Matlab

Converts normally distributed z-statistic to one- or two-tailed p-valueby integrating the standard normal pdf. If no "tails" value is specified, z2p computes the two-tailed value by default. The output p is the same size as z, which can be a scalar, vector, or matrix. Inputs:z: normally... Platforms: Matlab

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... Platforms: Matlab

Euler_Phi.zip is a suite of the foll Programmes :1) Euler_Phi (n) returns the no of positive integers less than n which are prime to n.2) a_k_mod_m_LCM_Method (a, m, k) : Imagine computing mod(14^26, 45) or mod(56^3005, 1125).This programme computes a_k_mod_m = mod (a^k, m) when a and m are...

Given a positive integer specifying size (N), this code will compute an example latin cube, a 3 dimensional extension of the latin square in which each orthogonal slice through the cube is itself a latin square.Note that the cube created is not an example of a /balanced/ latin cube, rather a...

The idea is to give more emphasis in some examples of data as compared toothers by giving more weight. For example, we could give lower weights tothe outliers. The motivation to write this function is to compute percentilesfor Monte Carlo simulations where some simulations are very bad (in terms... Platforms: Matlab

In many experimental settings in the life sciences, aggregated count data needs to be analyzed, for example, the number of mites on leaves of a tree, or the number of parasites found in hosts. This data is often well-described by a negative-binomial distribution. Although Matlab's statistical... Platforms: Matlab

Convert a single positive numeric scalar value into a string giving that value as the multiple of an IEC/ISO binary prefix. The binary prefix may be selected to be either the full name or the symbol, the symbol is default.The function automatically uses the lowest suitable binary prefix. Platforms: Matlab

Matlab doesn't provide the values of n! when n>170, but this code can evaluate the logarithm of of n! with absolute accuracy of 1e-12 or better, and relative accuracy of 1e-15 or better. The following codes employ Stirling's integration formula of Gamma function. Platforms: Matlab

Calculates the min and max of a positive triangular distribution given a standard deviation (sigma) and assuming the mode = 1.This function can handle single value,vector or matrix inputs of sigma. For sigma > 1/sqrt(6), the distribution will be asymmetrical with minimum = 0 and mode = 1. Platforms: Matlab

This submission demonstrates how to write a level-2 M-file S-function with a variable sample time.The block samples and holds an input signal were the inter-sample period is specified by another input signal (and may vary from time period to time period).Each step size must be positive or an...

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... Platforms: Matlab

For negative and pisitive data.If you have part of your data with a negative sign, you can try this analysis to find and plot the Weibull Distribution. FOr positive data runs very well. Platforms: Matlab

Y = UPSIDEVARIANCE(Y) returns the upside variance for columns of variable Y.Y = UPSIDEVARIANCE(Y, m) returns the upside variance using vector m as expected value for columns of variable Y.====================================================Upside variance is defined as the average sum of squared...
