1%% MEALPix for the HEALPix User
2%% MEALPix function names are derived from their HEALPix counterparts.
3% MEALPix functions are typically camel-cased (e.g., <angDist_help.html
4% |angDist|>, or <nSide2nPix_help.html |nSide2nPix|>). Underscores in HEALPix
5% names are dropped in the conversion to MEALPix names.
6
7%% MEALPix functions accept array arguments
8% MEALPix functions exploit Matlab(tm)'s vectorization facilities to
9% allow for the processing of arrays of pixels, direction vectors and
10% position angle vectors via a single function call. For example, the
11% MEALPix implementation of <angDist_help.html |angDist|> accepts mixed arrays of
12% cartesian direction vectors, angular position vectors, and ring or nest
13% indexed pixels for either argument.
14
15%% MEALPix indexes pixels from 1
16% HEALPix pixels are indexed from 0. In keeping with the Matlab standard
17% MEALPix pixels are indexed from 1. MEALPix pixels are indexed from 1:
18% i.e., MEALPix pixel number n corresponds to HEALPix pixel number n-1.
