Description: Tcl procedures to manipulate vectors and matrices.
User can mix vectors and arrays in linear algebra operations.
Currently at version 1.0 .
Procedures cover manipulation of vectors and matrices such as
scaling, concatenation by rows or columns, subsetting by
rows or columns, formatted printing, transpose, dot product,
matrix multiplication, solution of linear equation sets,
matrix inversion, and eigenvalue/eigenvector solutions.
Sophisticated operations such as evaluating a custom procedure
against each element of a matrix are easily possible.
The package contains a worked Principle Components Analysis
problem based on Section 6.5 of the SEMATECH/NIST Statistics Handbook,
