Computes the Gauss hypergeometric function 2F1(a,b;c;z) and its derivative for real z, z<1 by integrating the defining differential equation using the Matlab differential equation solver ode15i.
If 2F1 is to be evaluated for many...
This is a very simple, short Sudoku solver using a classic brute-force approach.
What makes it nice is the purely arithmetic one-liner computing the constraint c (the sequence of already used digits on the same row, same column, same...
Just a little bit of hack: a linear equations solver using eval and built-in complex numbers:
>>> solve("x - 2*x + 5*x - 46*(235-24) = x + 2")
QUADPROG2 - Convex Quadratic Programming Solver
Featuring the SOLVOPT freeware optimizer
New for version 1.1:
* Significant speed improvement
* Geometric Preconditioning
* Improved Error Checking
This program solves quadratic equations. Type in the coefficients for x^2 and x and the constant to get your quadratic equation and you will then be given the roots of the equation. If "b2 - 4ac" is negative, you'll be given the results...
