how to index an array

[05091975]

Dear list,

I would like to index an array in fortran. ideally it should look as follows where 'i' is the index:
x_i(nx,ny)

This shall help me to run through the index i to get arrays of different dimensions e.g.
i=1: x_1(10,5)
i=2: x_2(9,10)
i=3: x_3(5,2)

Cheers,
xian

You can do that only with derived types :

type matrix
  real, allocatable :: m(:,:)
end type

type(matrix) :: x(3)

allocate(x(1)%m(10,5), x(2)%m(9,10), x(3)%m(5,2))
...
