Eigenvalue

This is the home page of SLEPc, the Scalable Library for Eigenvalue Problem Computations. SLEPc is a software library for the solution of large scale sparse eigenvalue problems on parallel computers. It is an extension of PETSc and can be used for either standard or generalized eigenproblems,...

Two primary files are used for the CSP: csp.m is one file, and csp2.m is by another author. Csp.m requires spatfilt.m to work. The eigenvalue matrix test can be passed, but the U1 and U2 matrices are not equal. Any feedback would be welcome.

Let us assume the signal model:Y(k)=HX(k)+B(k)This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources. See reference [CHE91] Chen....
