Re Mathematica 5.2.0.0.
This code displays the component differences of matrix subtraction (A-B):
A = {{1, 2}, {3, 4}};
B = {{5, 6}, {7, -8}};
Map[MapThread[HoldForm[#1 - #2] &, {A[[#]], B[[#]]}] &, Range@2]
As desired, the output is {{1 - 5, 2 - 6}, {3 - 7, 4--8}}.
Two questions:
- What's a better way to do this?
- How can I replace the -- by +?
Thankx.
Bruce
