Function that convert geographic coordinates to North azimuthal equal-area map with 25 km
resolution pixel (EASE-Grid projection or NL). That projection is used mainly in remote sensing and cover the northern hemisphere.
John's Mutant contains a compiler for the mutant language. It is written in python, and emits NASM source code for 16bit DOS, x86 Linux, and x86_64 LInux. This is the successor to the Burapha Compiler Kit.
This short comparison by John Lim explains what he likes about PHP vs ASP and why his company is considering switching their language of choice.
I updated John Bair's xml2obj to allow better support of actually parsing xml files. Some of the information for this came from Uche Ogbuji's articles on the web. Enjoy.

Nonlinear median smoothers were popularized by John Tukey some years ago. The M-files in this suite are the embodiment of several. Rows or columns of a data matrix are smoothed individually. A contents file gives details and sample code.
This particular Direct Calculation Method is referenced from: J Hu "Radio Frequency Front-End Measurement and Modeling," Ph.D. dissertation, North Carolina State University, Raleigh NC, 2011.
This function takes as input angle measurements in the earth-coordinate system (0 degrees = NORTH, 90 degrees = EAST, 180 deg = SOUTH, 270 deg = WEST), and converts these angle measurements to the math-coordinate system (0 degrees = EAST, 90 deg =...
