Complex Grapher is a graphing calculator to create a graph of complex function. 3D function graphs and 2D color maps can be created with this grapher. You can input complex functions in the form of w=f(z) (where z=x+yi) directly before creacting graphs. Graphs can be copied and saved in the format of bitmap.

Although many things such as emotion and thought may be difficult to measure, some things are much easier to quantitize. Measurement Converter aids in converting one measurement to another similar measurement. Why people care so much about measurements and coversions still remain a mystery to one such as myself. I am convinced however that there could be a useful purpose for it.

CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called "curve fitting".
Quickly Find the Best Equations that Describe Your Data:
Curvefitter gives engineers and researchers the power to find the ideal model for even the most complex data, by putting a large number of equations at their fingertips. Curvefitter's builtin library includes a wide array of linear and nonlinear models from simple linear equations to high order polynomials. Curve fitter's stateoftheart data fitting includes the following capabilities:

The program allows you to solve algebraic equations in the automatic mode. You just enter an equation in any form without any preparatory operations. Step by step Equation Wizard reduces it to a canonical form performing all necessary operations. After that it determines the order of the equation, which can be any  linear, square, cubic or, for instance, of the 7th power. The program finds the roots of the equation  both real and imaginary.

Pulse shaping filter program that finds the polezero locations of a transfer function, H(s), for a matched filter. H(s)
equals a desired signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency.
Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay.

Goldengem is considered to be one of the best of the neural network stock prediction programs. It is a simple nononsense program, containing a sophisticated mathematical calculation, which has been very successfully used by a few top traders. Its StockDownloader downloads free data. Select tickers, in capitals, separated by commas, including any that may influence the price you wish to analyze. Press Load then Run. Select your ticker on the right. Select a number of days on the slider. You will see three traces going across the graph. The red trace is the historical price of your chosen ticker. The blue trace is a copy of this, advanced by the number of days on the slider.
The green trace is the neural net's attempt to match the blue curve, but using all loaded prices and volumes from the earlier time indicated by the red trace. Raise the sensitivity until the green and blue curves begin to match, and leave it running.
After a while, you can lower the sensitivity. If the green curve still matche ...
