Inverse Logarithm

This function computes at (Xi,Yi) unknown locations the IDW (w P=1, Q=1 yields interpolation at one point --> P>1, Q=1 yields interpolation at a vector of points --> P>1, Q>1 yields interpolation at a (ir)regular grid of points======================================== INPUTS Xc: (mandatory) [Nx1]...

The code implements the so called Faddeev-Leverrier algorithm to compute the coefficients of the characteristic polynomial of a given matrix and to get the inverse of the matrix without extra cost.

The conjugate gradient method aims to solve a system of linear equations, Ax=b, where A is symmetric, without calculation of the inverse of A. It only requires a very small amount of membory, hence is particularly suitable for large scale systems.It is faster than other approach such as Gaussian...

Numerical solutions for the conversion of an isothermal axially dispersed plug flow reactor accomplishing first and second order reactions are obtained. The Danckwerts boundary conditions for the so-called "closed" configuration are used. We use the shooting method since it is a...

This program is based on the method published by O'Reilly & Rueda (see program for more details for reference). Confidence level (i.e. alpha value) is chosen,and if the number of AD test stats > critical value exceeds alpha, H0 is rejected.The program requires 3 input files:2 of these files are...

The function is much faster than Matlab's native (dct, idct, dct2, idct2). It also allows N-D (multidimensional) input.Example:x=randn(100,200,300);y=mirt_dctn(x); % forward DCTx=mirt_idctn(y); % inverse DCTFind more at my home page:http://www.bme.ogi.edu/~myronEnjoy and comment below if you like...

When interpolating a multivalued function (more than one y for each x), interp1 produces, at best, an error (if there are identical x data), and at worst, garbage (see the attached image). This function performs meaningful interpolation of a multivalued function, when the inverse (x = g(y)) is a...
