Inverse Matrices

The m-file finds the elimination matrices (and scaling matrices) to reduce any A matrix to the identity matrix using the Gauss-Jordan elimination method without pivoting. Using the matrices gotten it computes the inverse of the A matrix.

Geo::Inverse is a Perl module to calculate geographic distance from a lat & lon pair. SYNOPSIS use Geo::Inverse; my $obj = Geo::Inverse->new(); # default "WGS84" my ($lat1,$lon1,$lat2,$lon2)=(38.87, -77.05, 38.95, -77.23); my ($faz, $baz, $dist)=$obj->inverse($lat1,$lon1,$lat2,$lon2);...

Kriging and inverse distance are popular interpolation methods, especially in earth sciences. There are some routines already available on matlab but are severely limited by matlabs memory constraints. By using gstat to handle interpolation and variogram modelling, very large datasets are easily...
