Multi-shift CGLS solves the systems of linear equations (A *A+TAU(I)*EYE(N))*X(:,I)=A *B (I=1:L) for X with the multishift CGLS algorithm. The right hand side (column) vector B must have length M, where the coefficient matrix A is M-by-N. TAU is a vector of reals (the shifts) of length L. For a short demo run main.m
