如何在fortran中获取数组的起始索引

Question

在fortran中定义一个数组

real, dimension(a,b) :: matrix

如何在给定'矩阵'的情况下获得'a'和'b'？

Answer 1

阅读关于内在功能size,shape,lbound和ubound.

http://gcc.gnu.org/onlinedocs/gfortran/SHAPE.html

http://gcc.gnu.org/onlinedocs/gfortran/SIZE.html#SIZE

http://gcc.gnu.org/onlinedocs/gfortran/UBOUND.html#UBOUND

http://gcc.gnu.org/onlinedocs/gfortran/LBOUND.html#LBOUND

可能你想size(matrix,1)和size(matrix,2)或ubound(matrix,1)和ubound(matrix,2).
