Function Prostate Gland

Functions NELSONFUN and NELSONFIT evaluate and fit (with non-linear least-squares) the Nelson-Siegel function, a popular yield-curve approximation device.

A simple function to write some text string to a file. Usage is the opposite of Matlab's native fileread function.See also "fileappend."-jqw

This function normalizes the columns of a given matrix. That is it makes l2 norm of each column to 1.

This function performs SAHN clustering (like linkage.m in the Statistics Toolbox) but allows users to define their own inter-cluster distance function. This function is thus more flexible than linkage.m (albeit a lot slower).(C) 2010 by David A. Snyder. Support for writing this code provided by...

This script allows you to graph any function you enter on the scale of your choice, assuming you use the correct javascript syntax.For example, to use Cos x, use Math.cos(x). Or, for x^2, use Math.pow(x, 2), etc.

This modification of fminsearch solves an issue with this simplex implementation when the function to minimize is smooth at a high scale, but rough at a low scale, i.e. when plotted with the parameters axis being (?10,10), there is a clear global extremum, but when zoomed (-0.1,0.1), the function...

WHOSBETTER is a function that sorts the WHOS output according a user defined input (ie name, size, bytes, type etc.). The output also includes the FULL size rather than the #-D labels that TMW prefers. The output is also human readable and incorporates the use of b (byte), kb (kilobyte), Mb...

This function can be very handy. Consider a case where you wish to analyze data, with different functions. In order to do so, you must write many code lines where you apply all the functions to the data. And this process tends to repeat itself for several data elements, and with varying...

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...
