Matrix: each, all?, none?, each_with_index, ....
There is Matrix#collect, but it would be useful to have Matrix#each and include Enumerable.
All methods that return anything else than an array are completely natural: Matrix#all?, Matrix#any?, Matrix#count, Matrix#none?, etc...
Others can be left alone or undefined (#sort, #drop, ...)
Matrix#each_with_index should go over all values, and yield value, row and column
Currently, some basic operations are quite a bit more difficult than they could be. An example: to check if a matrix is composed of Integer:
# Currently, need to build an intermediate array
m = Matrix[...]
integral = m.row_vectors.all? do |row|
# Could be
integral = m.all? &:integer?
I'll gladly provide precisions on each method and make a patch.
