Answer 1

阅读关于内在函数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

也许你想size(matrix,1)和size(matrix,2)或ubound(matrix,1)和ubound(matrix,2)。
