See the attached sheet.

The call to Vo() with matrix arguments should get the same answer as the individual evaluation, also included in the sheet, but it does not.

Hello,

No, it is not a bug - just a SMath feature. You divided a scalar (RU) with a matrix (RL), that is wrong. Reciprocal of a matrix gives its inverse, not the reciprocal of its elements as you wanted.

Please see the attached corrections

Regards,
Radovan

Thanks for the correction. This one might be a good addition to a Gotya section on the wiki if it is not already there.
