 Easy Equation Solver Easy Equation Solver is a simple and easy to use program for solving equations. The program can solve: Quadratic and Cubic Equations; Equation with 1, 2 and 3 Unknowns; Determinants 2x2, 3x3, 4x4; Inverse of a 2x2, 3x3 and 4x4 Matrices. You can create the   Actual Fractions From the developer: "Actual Fractions is advanced calculator for simple fractions. With this calculator, you can do operations with fractions, with the integer parts, numerators and denominators. Includes four rules of arithmetic, 'Reduce fractions', 'Trun   Maxima and Minima Finds the relative maxima and minima of multivariable functions. It can fully explore defined intervals to search for multiple solutions or quickly find solutions starting with random seeds. You may predefine constants and specify the error bound for the r   RPN Engineering Calculator Programmable RPN calculator contains over 250 solutions with 6 keypads: standard, engineering, binary, magnetics, trig, and convert. You can select fixed, scientific, or engineering notation and degrees, radians, or grads for your calculations. Has a runni   SuperCon 2000 From the developer: "SuperCon 2000 contains 67 physical quantities and 760 units. Since the conversion factors are of significant figures of 15, based on the strict base conversion factors such as foot to meter, pound to kilogram, BTU to joule, gallon to c 

 The Lucent Calculator A windows  calculator, that also can handle mathematical expressions with variables. The input always can be verified and/or modified. For every function a tooltip help is available, so a formulary is not necessary. Up to 30 formulas and variables can be   Graph This program is for drawing graphs of mathematical functions in a coordinate system. Graphs may be added with different color and line styles. Both standard functions, parameter functions and polar functions are supported. It is possible to evaluate a func   AVD Mass and Volume Calculator AVD Mass and Volume Calculator is just the thing for measuring physical parameters of composite objects in 3D. It calculates weight, volume and mass for the figures of various shapes. The process of calculation is quite simple: after you select the object   Neural Networks  DCT for Face Identification Neural Networks  DCT for Face Identification. Matlab source code. High information redundancy and correlation in face images result in inefficiencies when such images are used directly for recognition. Discrete cosine transforms are used to reduce image i   Effect Size Calculator A standalone Windows program that calculates effect sizes (Cohen's d, r, Glass's delta, Hedges' Unbiased d, Common Language Effect Size, mean difference, pooled standard deviation) given appropriate group means and standard deviations.
