fortran里面算矩阵AX=B（即输入A、B矩阵,求X）,且A,B都为复数矩阵,请问调用的子函数名是哪个?
只清楚当A,B矩阵都为实数矩阵时,从其函数库里面调用MATMUL（）这个子函数.当A,B都为复数情况时,该用哪个子函数?

Answer 1

一样的.matmul 允许 real integer complex 等各种类型.
MATMUL
Transformational Intrinsic Function (Generic):Performs matrix
multiplication of numeric or logical matrices.
Syntax
result =MATMUL(matrix_a,matrix_b)
matrix_a
(Input) Must be an array of rank one or two.It must be
of numeric (integer,real,or complex) or logical type.
matrix_b
(Input) Must be an array of rank one or two.It must be
of numeric type ifmatrix_ais of numeric type or logical type ifmatrix_ais logical type.
