Format - Fortran Matrix Abstraction Technique. Volume II. Supplement V. Description of Digital Computer Program - Extended.

Abstract

The FORMAT system has been augmented with new capabilities applicable to elastic stability and dynamic analyses and has been modified to improve operating efficiency and user convenience. A new large order eigen solution module and a module to evaluate matrices representing specific forms of complex exponents of the natural logarithmic base e have been added. Efficiency improvements have been made to the matrix multiply, transposition and decomposition modules. In addition, the decomposition module has been modified to perform congruent transformations yielding the upper triangular form of the resulting matrix. The capability to create user defined leading diagonal or full rectangular matrices with constant element values has been added to the matrix card input module. The capability of modifying available work space parameters with user input has also been provided. (Author)
