Sine Function

Writes to file a sorted list of MATLAB functions for all MathWorks products installed on the machine (that the function is executed on). Denotes which functions are built-in to help with syntax highlighting.

parameter fun means function, x0 and x1 the interval of function where we search zeros.

Math Function Mania is a fun multimedia game that teaches functions, algebra and problem solving skills. Functions are very important in math! By mastering them, you will greatly increase your math skills. This game teaches you by the "hands on" method - you will discover how functions work by...

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


Platforms: Matlab

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 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...


Platforms: Matlab

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...
