Convert a specified Julian Date Vector to Greenwich Mean Sidereal Time (GMST). The expected input matrix may contain multiple dimensions. The output matrix will be in the same size as the input matrix. Warning: Use caution when using GMST as a substitute for Greenwich Apparent Sidereal Time... Platforms: Matlab

Two methods are provided -1) an automatic updation method which can be effectively used outside of a loop since it writes out a newton-raphson computation file from the parameters received.2) a manual file generation method; effective when the resulting file has to be called repeatedly in a loop.

"It takes from 10 to 15 years to bring a new drug to market?at a cost rapidly approaching $1 billion. A key contributor to these staggering costs is late-stage failure: Of every 250 compounds that enter preclinical testing, only five proceed into clinical trials, and only one will be approved by...

Based on the concept of the Taylor Table given in Fundamentals of Computational Fluid Dynamics by Lomax, Pulliam, and Zingg.Given the terms of the point operator, "TaylorTable" will determine the coefficients of the terms which minimizes the Taylor series error. It will also determine the Taylor... Platforms: Matlab

The method uses finite differences to solve Laplace equation and matrix inversion to solve the resulting system of linear algebraic equations. The rectangular plate has both dimensions set equal to unity. Each dimension is discretized and the total number of nodal points is equal to 29*29. To... Platforms: Matlab

This program implements the iterative algorithm in Khachiyan's paper "Rounding of Polytopes in the Real Number Model of Computation" to approximate the minimum volume ellipsoid circumscribing a non-degenerate set of points in arbitrary dimensions.It is basically like Nima Moshtagh's MinVolEllipse...

Data density can be hard to read from scatter plots due to overstriking. I therefore calculate data density at each pixel as the reciprocal of the sum of squared distance from each point, adding a fudge factor to prevent points actually within the pixel going to infinity.The resulting plot allow...

GUI for improving resolution of lower resolution image using higher resolution image using RGB-to-HSI conversion.Images have to be spatially co-registered.Monochromatic (gray scale) low resolution image is converged to colored image by false color mapping to "hot" color scheme. This RGB image is... Platforms: Matlab

A GUI for solving sudoku puzzles (including those supplied by you) with various levels of help, from none (other than recording your choices and objecting to obviously wrong choices), to checking the number of solutions (which avoids struggling with puzzles that have more than one solution), to...

The two inputs X and Y are vectors defining a set of N points. The function uses Lagrange's method to find the N-1th order polynomial that passes through all these points, and returns in P the N coefficients defining that polynomial. Then, polyval(P,X) = Y.R returns the x co-ordinates of the N-1... Platforms: Matlab

When interpolating on a given data set, convhull is used to set the boundaries of the interpolation area. Because convhull only minimizes the outline length, there might be interpolation lines which are unwanted (see figure).hullfit tries to minimze the polygon area instead resulting in a hull...
