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...

XI = findX(X,Y,YI) estimates the XI values at which the dependentvariables Y reach or cross a specified target level YI (scalar value). If there are multiple solutions, findX finds all of them. It may be seen as the "inverse" operation of the MATLAB's functionINTERP1, under 'linear' method.X is a...

This function plots unitvectors X Y and Z or (e1, e2, e3) from an origin.This function is fairly robust in that it can take 2 types of input. It can take a transformation matrix of the formtrMatrix = [1 0 0 0; pos' unitx' unity' unitz'] as:fcn_plotUnitVectors(trMatrix).Or it can take it as a...

PGFHIST2D(X, Y, W) will save a PNG file representing the 2D histogram created from data points specified by X and Y with weights specified by W. The vectors X, Y, and W must have the same number of elements. The text to include in a Latex file to produce the histogram is displayed. Valid options...

BLOCK_LEVINSON(Y, L) solves the matrix equation T * x = y, where T is a symmetric matrix with block Toeplitz structure, and returns the solution vector x. The matrix T is never stored in full (because it is large and mostly redundant), so the input parameter L is actually the leftmost "block...

This program checks whether a point (x,y) lies inside,outside or on a circle defined by 3 other points.Syntax: iscircle(X,Y,x,y), where X=[x1 x2 x3] and Y=[y1 y2 y3]. Thus, a circle can be made out of these 3 points-->(x1,y1), x2,y2)&(x3,y3).Program checks whether point (x,y) lies inside,outside...
