Its always better to attach the worksheet itselft rather than just a picture.

 

Are you aware that Prime uses two different types of indices - literal indices and vector/matrix indices?

Chances are that you used the wrong ones.

 

A vector index is just an integer. So you could not use something like z.k1 but rather would use z.10*k+1

Furthermore you have to know that if you define z.11:=... you are defining a 12 element vector (assuming you have not changed the value of ORIGIN which is 0 by default). Unless you have them defined before, all other elements of the vector z (z.0, z.1 ... z.10) are set to zero.

ok..so I should use the literal version then?..how do i access/implement that? I just used "operators"--> and picked the one with the
subscript matrix index. 
Sorry about the pic..i was hoping that would be clear..

No, the vector/matrix indices would be the correct ones to use, but it could not be seen from the pic which you used where.

So again, upload the sheet for further help.

Please upload your Mathcad Prime worksheet here.
