I'm having a problem figuring out how to do some math on a subset of a vector. I have some data that I want to store in a variable (range or vector). I want to be able to perform some simple math on portions of that variable, but it's not working the way I'd expect.
(I apologize, I don't know how to add mathcad notation in this forum)
Example.
I have 4 elements I'm storing in a variable called row (row = 1,3,7,15) using range variables ii=0..3
I want to take the 2nd through 4th element and subtract off the 1st through 3rd element and store that in a new variable which would have the result of newrow = 2,4,8
I thought I could just do the following
jj=1..3
kk = 0..2
newrow[kk = row[[jj - row[[kk
but I get an error saying jj should be an integer.
What am I missing?
Thanks!
