Description:

Keywords: BLAS, Linear Algebra, optimization, FFT,
        interpolation, SVD, lazy image, vector promise,
        pseudoinverse, regularization,
        C++, class library

Hot points:
        - _efficient_ and _fool-proof_ implementations of level 1 and
2 "BLAS" (element-wise operations + various multiplications)
        - transpositions and determinant evaluation/inversion
        - operations on a single row/col/diagonal of a matrix
        - Lazy vector and Matrices (promises) , and ElementAction
iterators for fast sweeping actions
		 - radix-2 DFT of a real or complex sequence, or sin/cos 
complex Fourier
	      integral of an evenly tabulated function.
		   Inverse of a transform restores the original
		   function with the relative error of 1e-6% 
        - Hooks-Jeevse multidimensional optimization
        - Aitken-Lagrange interpolation over a grid of uniform or
arbitrary mesh
        - *Singular Value Decomposition* of a rectangular matrix, with
an application to solve Ax=b, where A does not have to be square, and
b does not have to be a vector. In a case of a rectangular matrix A,
this effectively solves a least-squares problem.
        - Brent's efficient univariate optimization and root finding
(with a guaranteed conversion)
        - with a validation code to verify everything
        - with a rather commented source and DR8 projects

A *big* README file tells much more what it all is and how to use it
