NEWLIN:A DIGITAL COMPUTER PROGRAM FOR THE LINEARISATION OF SETS OF ALGEBRAIC AND FIRST ORDER DIFFERENTIAL EQUATIONS

摘要

The techniques normally used for linearisation of equations are not amenable to general treatment by digital computation. This report describes a computer program for linearising sets of equa¬tions by numerical evaluations of partial derivatives. The program is written so that the specification of the non-linear equations is the same as for the digital simulation program, FIFI, and the linearised equations can be punched out in form suitable for input to the frequency response program FRP2 and the poles and zeros program ZIP.nFull instructions for the use of the program are given and a sample problem input and output are shown.
