Curl Of A Vector Field

Calculates the geometric mean of a vector X (first argument) weighted by the values of another vector W (second argument). It may be already available, but I didn't find it, so here it is, just in case.

The idea is to give more emphasis in some examples of data as compared toothers by giving more weight. For example, we could give lower weights tothe outliers. The motivation to write this function is to compute percentilesfor Monte Carlo simulations where some simulations are very bad (in terms...

This function will return true if the first input structure contains the field in the second input string and in turn that field has the field given in the third input string and so on. This allows A.b.c = 2; to be checked as:isfieldRecursive(A,'b','c')ans =1Which would return false if either b...

Given a desired value "y0", this function finds all the elements "y" in a vector whose values are the closest to "y0" in the whole vector, and also the positions "xi". So, the output is a set of points [xi,y0] given in two vectors, one for the values and another one for the positions.The inputs...
