Hallo,

I have a structure M:

M = {{{{a, b}, {e, f}}, {{c, d}, {g, h}}}, {{{k, l}, {o, p}}, {{m, n}, {q,
r}}}}


M//Dimensions

gives

{2, 2, 2, 2},

(or more general {n1, n2, m1, m2}; M is the result of the BlockProcessing
function from the Image Processing package)

Does anyone know an elegant way of 'flattening' M to give

{{a, b, c, d}, {e, f, g, h}, {k, l, m, n}, {o, p, q, r}}

with dimensions {4, 4} (or more general {n1*m1, n2*m2})?


Thanks for your help,


Maarten
