Calculate Cubic Meter

This is free software that adds several spline and linear interpolation functions to Microsoft Excel. It is simple to use because the new functions work just like all other existing Excel functions. Spline functions include cubic spline, bessel spline, and 'OneWay' spline (which is a monotonic...

A free CPU meter for your desktop, along with three more dials for memory, disk partition and process usage. This utility can continuously and simultaneously monitor these key computer parameters, displaying them on big dials for easy observation, as numeric percentage and analog hand rotation....

Overtime meter is a small wxPython program which stays in your tray and counts the minutes your spend at work. Then by the end of the month you can tell your boss exactly how much extra money he should pay you.

The zip file contains functions to calculate an Ambiguity Function (XAMB), Upsampled and Interpolated Correlation (XCORRU), and Coherence Function (XCOH). A prefilter can be specified in each function to "sharpen" correlation peaks.XAMB calculates an estimate of the (cross-)ambiguity function. A...

PP = PCHIPD(X,Y,D) provides the piecewise cubic polynomial which interpolates values Y and derivatives D at the sites X. This is meant to augment the built-in Matlab function PCHIP, which does not allow the user to specify derivatives.X must be a vector.If Y and D are vectors, then Y(i) and D(i)...
