CondensedMatrix problem

[victor-gil-sepulveda]

This does not work:

N = len(elements)
new_matrix = CondensedMatrix([1.]((N(N-1)/2)))
for i in range(len(elements)-1):
e_i = elements[i]
for j in range(i+1,len(elements)):
e_j = elements[j]
new_matrix[i, j] = old_matrix[e_i, e_j]
return new_matrix

Probably because of the data returning policy, the condensed matrix can be modified but the returned array is not.
