Description

            Imsls provides iterative methods for sparse linear systems of equations.

Features
--------

 * imsls_bicg: BIConjugate Gradient method
 * imsls_bicgstab: BIConjugate Gradient STABilized method
 * imsls_pcg: Conjugate Gradient method
 * imsls_cgs: Conjugate Gradient Squared method
 * imsls_cheby: CHEBYshev method
 * imsls_gmres: Generalized Minimal RESidual method
 * imsls_jacobi: JACOBI method
 * imsls_qmr: Quasi Minimal Residual method
 * imsls_sor: Successive Over-Relaxation method
 
Support:

 * imsls_benchmatrix : Test a matrix against all solvers.
 * imsls_getpath : Returns the path to the current module.
 * imsls_lehmer : Returns the Lehmer matrix.
 * imsls_makefish : Returns the Poisson matrix.
 * imsls_matgen : Returns a test matrix.
 * imsls_nonsym : Returns a non symetric matrix.
 * imsls_spdiags : Extract and create sparse band and diagonal matrices
 * imsls_split : Sets up the matrix splitting for Jacobi and SOR.
 * imsls_tester : Test all algorithms
 * imsls_wathen : Generates a random finite element matrix.

Compatibility:

 * mtlb_bicg : Solves linear equations using BiConjugate Gradient Method with
preconditioning.
 * mtlb_bicgstab : Solves linear equations using BiConjugate Gradient Stabilized
Method with preconditioning.
 * mtlb_cgs : Solves linear equations using Conjugate Gradient Squared Method
with preconditioning.
 * mtlb_gmres : Solves linear equations using Generalized Minimal residual with
restarts .
 * mtlb_pcg : Solves linear equations using Conjugate Gradient method with
preconditioning.
 * mtlb_qmr : Solves linear equations using Quasi Minimal Residual method with
preconditioning.

This version v0.1.1 is correctly packaged.
I tested this with Windows 32bits and Scilab 5.3.2.
