哪位大侠知道Fortran中求逆矩阵的调用函数

实在不好意思，我是Fortran的新手，请问这个IMSL数学库在哪

Answer 1

需要用IMSL数学库，“USE NUMERICAL_LIBRARIES”
矩阵求逆函数：LINRG/DLINRG (Single/Double precision):
Usage:
CALL LINRG (N, A, LDA, AINV, LDAINV)
Arguments:
N — Order of the matrix A. (Input)
A — N by N matrix containing the matrix to be inverted. (Input)
LDA — Leading dimension of A exactly as specified in the dimension statement
of the calling program. (Input)
AINV — N by N matrix containing the inverse of A. (Output)
If A is not needed, A and AINV can share the same storage locations.
LDAINV — Leading dimension of AINV exactly as specified in the dimension
statement of the calling program. (Input)

这个…一般的fortran编译器是不自带IMSL库的，除非你安装了visual fortran专业版。这个网上似乎也没的下。推荐你使用编译器的自身集成的数学库，如vf的CXML.可以使用帮助，有帮助文档的。但这样也有些麻烦，你可以自己写一个，不难的。
