How to assign vectors to a function - MathCad Prime 9

Hi,

I have changed the coordinates a, b ,c into column vectors then you only need to index their position once.

Note index starts at zero by default.

Changed function to use the two elements of a vector x

Cheers

In Prime a vector only is a column vector and you need just one index to specify one of its components.

row vectors are considered 1 x n matrices.

But of course you may define your points in the form of row vectors. You simply need to adopt the calculations accordingly or you could always use the transpose operator to turn a row vector into a column vector.

Here are my two cents
