real, dimension(a,b) :: matrix 

陣列如何獲得「a」和給定的「B」「矩陣」？

Answer 1

閱讀關於內在函數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

也許你想size(matrix,1)和size(matrix,2)或ubound(matrix,1)和ubound(matrix,2)。
