LinearAlgebra 1.2.0

Tools for working with matrices and vectors.

This module contains some tools for linear algebra. It contanis classes
to define matrices and vectors, and a number of functions for working
on those matrices and vectors. It is intended for mathematical and
scientific use. It saved me a lot of time in a linear algebra class.

classes:

vector
matrix: two-dimensional collection stored in row-major order

functions:

AxApproxB: solves Ax approximately equal to b; for use when the rows of
matrix b are not in the column space of A
axpy: ax+y where a is a scalar, and x and y are vectors
bestfit: used to find a line of best fit from given points
colVec: makes a matrix with one column
det: returns the determinant of a square matrix. Can return a cross
product if the top row contains the unit vectors.
dot: returns the dot product of two vectors
GaussJordan: solves AX=B, where matrices A and B are known and X is
returned. If B is not in the column-space of A, use AxApproxB.
identityMatrix: makes an identity matrix of a given size
linearCombination: returns a linear combination based on a list of scalars
and a list of vectors
mmMult: matrix-matrix multiplication
mvMult: matrix-vector multiplication
rowVec: makes a matrix with one row
transpose: transposes a matrix
unitVector: constructs a unit vector
v: wrapper around vector instantiation
zeroMatrix: makes a zero matrix of a given size
zeroVector: makes a zero vector of a given size

Help can be obtained by using standard help function, e.g.

>>>import LinAlg
>>>help(LinAlg)

will show what all of the classes and functions in the LinAlg module do.
Of course one can use help on any specific class or function.
