Digits Of Pi

The MATLAB file contains a method to find the value of pi. This is just an extension of the general method of finding pi from within a circle. It uses 3D-matrices and some more stuffs, which can be very helpful for educational purposes. Also, do change the values in the file, to see for yourself,...

Before there was floating point, or a way to write zero, or algebraic notation, Archimedes bounded the value of pi by estimating the perimeter of regular polygons inside and outside the circle. His computation is repeated and explained here using MATLAB.

A circle of radius 0.5 is inscribed inside a square with side length 1.Script picks N points at random inside the square. It then checks to see if the point is inside the circle and then generates a figure in which the points ''in'' and ''out'' are plotted in different colors. Say we have M...
