Identity Matrix

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.

Canonical discriminant analysis is a dimension-reduction technique related to principal component analysis and canonical correlation called canonical discriminant analysis. It derives the canonical coefficients parallels that of one-way MANOVA and it finds linear combinations of the quantitative...
