This submission contains the code used to verify the claims made about pSpace, NP and co-NP classes in the four element case. The original paper that references these claims can be found at http://drops.dagstuhl.de/opus/volltexte/20....Paper.2367.pdf.To run the verification first ensure that you...

Intro: This function generates random samples for k Xi's where Xi>=0 and the sum Xi is fixed at g. We assume that X's are independent and follow an identical distribution with a CDF function myCDF(x) and an inverse CDF function myICDF(p). I needed a function that works for Xi>=0. So here it is....

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...

Amicable numbers are two different numbers so related that the sum of the proper divisors of the one is equal to the other, one being considered as a proper divisor but not the number itself. Such a pair is (220, 284); for the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110,...

Let d < N be a positive integer and define p = N/d. Let y_{1} be a point on the unit circle. Let R be clockwise rotation by the angle t = 2*pi/p. The generalized regular polygon {p} is given by the points y_{i+1} = R * y_{i}, and edges between points i and i+1.Example:polygon(9, 4, 1);

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...

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...

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...

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...

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...

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.

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.

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.
