Just a basic matrix multiplication error. Confused in using range of variables

11.jpgwhen i am using r=1 , it works good ( value of Vs) but i want to calculate for the range of values from 1 to 10. I already tried using in matrix form and semi colon form but still it is giving me error. Please help somebody22.jpg33.jpg

Re: Just a basic matrix multiplication error. Confused in using range of variables

Hi,

 

You cannot confuse a range variable with a single column vector.  One can be indexed into (the vector) one cannot (the range variable).  In Mathcad 14/15 these used to be displayed differently.  In Prime they are not.

 

Prime 4.0 enclosed with a pdf  .

I'm afraid you're confused.

You cannot see the difference between a range variable and a vector variable, unless you've chosen to use different tags for them.The difference will become apparent upon indexing the variable and evaluating it:

In Prime the options of tagging (labelling) variables are more limited than they used to be in Mathcad.

On the other hand, the difference between an index and a literal subscript is apparent in Prime upon selecting the expression. A grey [ is shown next to an index then.

Success!
