úÎ#e    None: Xto2DList turns a 1-d list to 2D list. to2DList :: E.Elem a b => Int -> [ b ] -> [[ b ]]µAlternative implementation of fromList. It accepts a flatten list of elements and number of columns. No tests are performed to check if number of elements in list are sufficient.Stack matrices horizontallly•Stack given matrices vertically. It uses the following property vstack [a, b, c ..] = ( hstack [a',b',c'.. ] )' where M' is transpose of matrix M. UTODO: This is computationally inefficient than implementing is directly like hstack.
