This GUI provides a visualization of the electromagnetic field induced by a current flowing in a straight wire. The tool also shows the current induced by a rectangular coil that is placed inside the electromagnetic field. The current is calculated using Ampere's Law and the Biot-Savart Law. This...

This toolbox can solve any of the 6 possible subproblems associated with an oblique spherical triangle, when only 3 of the 6 angles are known.The toolbox basically is an implementation of the set of tools developed in [Wertz, 2001], which aimed to fully automize the procedure and do away with the...

B3MSV Bidirectional Branch and Bound(B3) subset selection using the the Minimum Singular Value (MSV) as the criterion.Consider the following subset selection problem:Given a tall (m x n, m>n) matrix, A, to find n rows of A such that the resulted n x n square submatrix has the largest MSV among...

IMSHADE will plot a matrix representing topography as a 3-component color image, with intensity proportional to the magnitude of the topographic slope of each pixel. Optionally, it can take an argument for lighting angle to use the directional slope.The current colormap will be used, but future...

This function amplifies areas of high intensity and segments them using a front. The front is initialized on the convex hull (for speed) and erodes the map until it has converged on the edge of the areas to keep, maintaining edge geometry.The idea and title for this function come from Dr. Tong...

Estimates the noise standard deviation from an (MRI) image (2D) corrupted with Rician noise based on the skewness of the distribution. This method doesn't depend on the background for noise estimation. Can be used for MR images with and without background.Ref: Jeny Rajan, Dirk Poot, Jaber Juntu...
