XL Toolboxes

XLLinear Systems

This toolbox provides a set of functions for working with real and complex matrices which represent systems of linear equations. The various functions perform the following operations: Compute the LU factorization of a real general matrix and estimate its L1 condition number Compute the LU factorization of a complex general matrix and estimate its L1 condition number Compute the determinant of a real general matrix Compute the determinant of a complex general matrix Compute the inverse of a real general matrix Compute the inverse of a complex general matrix Compute the inverse of a real symmetric positive definite matrix Solve a real general system of linear equations Ax=B with iterative refinement Solve a complex general system of linear equations Ax=B with iterative refinement Solve a real system of symmetric positive definite linear equations Ax=B with iterative refinement Solve a real system of symmetric linear equations Ax=B with iterative refinement Buy today at SpreadsheetWorld.com
