这里给出的程序组装和解决对称正定方程满足有限元应用。该技术比标准的带矩阵算法更复杂，但在二维或三维元素具有角节点以外的重要情况下更有效。当有许多右侧时，如在自动化设计中，会包括一些辅助工具以提高效率。该程序的组织是参照图表，完整的符号，样本输入数据和阿萨FORTRAN打印输出的补充意见。
The program given here assembles and solves symmetric positive–definite equations as met in finite element applications. The technique is more involved than the standard band–matrix algorithms, but it is more efficient in the important case when two-dimensional or three-dimensional elements have other than corner nodes. Artifices are included to improve efficiency when there are many right hand sides, as in automated design. The organization of the program is described with reference to diagrams, full notation, specimen input data and supplementary comments on the ASA FORTRAN print-out.
