Function Grapher

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.

Visual Calculus is an easy-to-use calculus grapher for Graphing limit, derivative function, integral, 3D vector, double integral, triple integral, series, ode etc. Which can create 2D, 2.5D and 3D function graphs, animations and table graphs. 2D Features: explicit, implicit, parametric, and in...

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...
