Summation when j is not equal to i

Hello everyone,

Im trying to construct a matrix in Mathcad Prime 4.0 for a Newton-Raphson power flow solution, but im having trouble defining the elements where a summation with j≠i is needed.

Is there any way to handle this in MathCad?

 

Thanks in advance

Simple.

Multiply the argument of the summation with (i<>j)

where <> is the unequal sign.

And if course you need nested summations, one over all i, and one over all j.

 

Success!
