Hello,

I have two one dimensional matrix An & Bn

n= No of column of the Matrix

Please see the attachment, which is quite easy to understand what I want to achieve

Thanks

PS I am using Math CAD 14

Best answer by LucMeekes

Attached is a version that returns the result with units.

Note that Mathcad internally stores values with its internal representation of a unit. That's m2 (metres squared) for areas. If you want to display the result in mm2 (millimetres squared) you'll have to type mm^2 in the units placeholder following the result.

The calculated results should not differ for different input/output units, provided that you account for those units. So if both input vectors are given in mm2, you'll get the result (by default) in m2. Now realise that 1 m2 = 1 000 000 mm2.

Success!

Luc

Not to me. I understand how you get 0 as the first answer, and 600 as the second. Please explain the logic you use to get 0 as the third answer. It looks like this was calculated in an Excel spreadsheet, in which case please post the spreadsheet.

Hi Everyone,

I am still struggling with this Matrix Complex Subtraction

I am thinking it is more like a Boolean Subtraction, but I couldn't figure this out though.

May be somebody comes up with a genius solution !
