This vector class stores elements in a list and hence allows the 'vector' to grow dynamically. Common mathematical functions (sin, cosh, etc) are supported elementwise and so are a number of 'external' operations (dot for the inner product between vectors, norm, sum etc.).This class does not rely...

This is a fun, one player DHTML Phong (Ping Pong) game.It uses cos and sin to move the ball at a specified angle, and the ball's angle can be altered by moving the paddle faster and hitting it. Ball also speeds up the longer the ball is in volley. Script has been tested in IE6 , NS6 , and Opera 7 .

Some curve fitting or smoothing tools can benefit from knowledge of the noise variance to expect on your data. Kalman filters use this information, also some spline fitting tools. So I wrote a function to extract the noise variance from a signal vector. It also works on any specified dimension of...
