Tabled values returning non-tabled results

[lonicus]

For some reason whenever I multiply one tabel by another Mathcad 13 is retuning me the sum of all values instaed of another table. I have no pronblem with any other simple operators, why is it doing this?

 

[GregLocock]

which operator did you use?

multiply, or "*"

basicaly, I have defined a table as a variable D, if i multiply D by itself, or any other table I get a result like the following:

D*D=10.451, where D=1, 3, 4, 2, 6,... (values are made up here but you get the idea)

or D*d=2.345 where D is the same as above but d=3,6,1,4,8 or such

I want a result that reads D*D=1,6,8,4,36... (value 1 gets multipled by itsef, then value 2 etc..

thanks for the help

You need to do it as an indexed operation.

Tables are basically the same as matrices. Your single column tables are vectors which when multiplied (dot product) yield a scalar value.

To get a table that has each element as the multiple of the elements of the original tables, use the vectorize operator, Ctrl+- after getting the editing lines (the little blue angle) under and to the right of both variables.

I guess that is what you want, even though in your example, 3*3 does not equal 6 and 4*4 does not equal 8.
