I have imported excel data and made column vectors from data. When I try to multiply elements with an index beginning somewhere in the range I get this.
Why do I get zero values and how might I eliminate this behavior?
Any help would be greatly appreciated.
By default vector indices start with number 0 and if you assign the vector element 5 a value, you are actually creating a 6-element vector. Elements #0 to 4 are set to 0.
So you might use index i-5 instead of i on the left hand side when you assign the multiplication result.
Other solutions like the usage of the "submatrix" function or the "trim" function are possible, too.
Furthermore you should move the return of the result from inside the loop to after the loop - it works the way you did, but its not good programming habit.
For future question you should consider attaching your worksheet and stating, which version of Prime you are using.
