Modifications of SUPORT, a Linear Boundary Value Problem Solver:Part I. Pre-Assigning Orthonormalization Points,Auxiliary Initial Value Problem,Disk or Tape Storage.

摘要

Some new capabilities of the code SUPORT,which solves linear two-point boundary-value problems are discussed. One modification now allows the user to pre-assign a set of orthonormalization points. In this mode of operation,the code does not check when orthonormalization should take place,so care must be taken in selecting the points to produce a satisfactory solution. Some guidelines are offered in using this option. Another capability allows the user easily to solve a boundary-value problem which depends on the solution of a nonlinear initial-value problem. This solution is achieved by simultaneous integration of all equations. Another capability allows the user the option of utilizing disk or tape storage for intermediate computations,and thereby reduce the in-core storage requirements for a large problem. 4tables.
