Algebra X And Y Calculators

The goal of VTP is to foster the creation of tools for easily constructing any part of the real world in interactive, 3D digital form. This goal will require a synergetic convergence of the fields of CAD, GIS, visual simulation, surveying and remote sensing. VTP gathers information and tracks...

About APC Tracker A Cocoa application for UPS devices in a network that powers specifically off Mac OS X and Xserve. It investigates the status of the UPS and will properly shut down the client computer once power gets interrupted. The revised design enables face-less operation in server...

Y = DCTN(X) returns the discrete cosine transform (DCT) of X.X = IDCTN(Y) returns the inverse discrete cosine transform (IDCT) of Y.Y = DSTN(X) returns the discrete sine transform (DST) of X.X = IDSTN(Y) returns the inverse discrete sine transform (IDST) of Y.X and Y can be N-dimensional.D =...

Fisher's exact test is a statistical test used to determine if there are nonrandom associations between two categorical variables[1]. The job of Fisher's exact test with 2 x 2 or 2x 3 contingency table is already easily done by others. However, the one with n x m contingency table hasn't found ,...

GRDWRITE2(X,Y,Z,'file.grd') will create a grid file containing the data in the matrix Z. X and Y should be either vectors with dimensions that match the size of Z or two-component vectors containing the max and min values for each. The file will be a COARDS-compliant NetCDF file, the standard...

I checked out a couple of projects out there, e.g. videoIO - but I didn't get lucky with it, so I did some very basic things on my own: * Most stupid way of implementationThe source provides the slowest and most stupid way for video processing, but it works: It starts ffmpeg (must be installed)...

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...

function [coef, RSquared]=plotdata(xi,yi,polyorder) A simple data plotting function, useful for inspecting x,y data. The function accepts data in the form of a single vector, a pair of vectors "x" and "y", or a single NxM or MxN matrix with the independent variable (x) in first row or column...

POLYFIT3(X,Y,N,NUL,W) finds the coefficients of a polynomial P(X) of degree N that fits the data, P(X(I))~=Y(I), in a least-squares sense. Any of the coefficients can be forced to be zero, and data can be weighted.NUL is a vector with coefficients forced to be zero in usual order.W is a vector...

With the default settings, BINNED_PLOT(X,Y) splits vector X into bins of approximately equal size, and plots each median against the median of the corresponding Y-values, as well as their inter-quartile range. X and Y must have the same number of rows or columns.This is useful to visualize...

Uses x,y coordinates to produce distance-based spatial weight matrices useful for spatial econometric regressions. The user is asked to input x and y coordinates, as well as a lower and upper bound threshold for the neighborhood.The code is adapted from a previous version by Shawn Bucholtz of the...
