Abstract : A computer program written in FORTRAN IV symbolic language for the in-core solution of large, sparse, unsymmetric systems of linear equations is presented. The efficiency of this program with respect to computer storage and arithmetic operations depends upon the system of equations at hand and the technique adopted for selecting the pivotal element are included so that the program user can choose the technique which appears to be suitable for the system of equations under consideration.
