umatrix v1.1.2

Changes and Fixes

• Removed from math import floor, using // instead.

• Fixed error in lesser traveled __getitem__ path that resulted in column and row index reversal.

umatrix v1.1.1

Patch

__setitem__ had an undefined variable and faulty logic in one of its lesser traveled if branches. The undefined variable was removed and the logic in the if branch amended.

New functionality

Deprecated

The size method has been dropped in favour of shape.
