The generalised inverse

  • M. James (a1)
Extract

If we have a system of m linear equations to solve, it is a great simplification to write them in matrix form

Ax = b ,

where A is an m x n matrix of coefficients, b is an m-dimensional vector of constants and x is an n-dimensional vector of unknowns.
