Publisher review:pcgnull - Preconditioned Conjugate Gradients Method PCGNULL Preconditioned Conjugate Gradients MethodX = PCGNULL(A) attempts to solve the homogenious system of linear equations A*X=0 for X such that NORM(X)=1.The coefficient matrix A must be Hermitian and positive semi-definite. If the null-space of A is more than one dimentional, i.e. A*X=0 allows multiple linear independent solutions, PCGNULL will still converge to one solution, namely, the orthoprojection of the initial guess to the null-space. Tested under MATLAB versions 5.1-5.3. Requirements: ยท MATLAB Release: R11
