Function with a Vector variable

Hello,

usually I define function as function of variables. The latter being scalar.

How can I define a function with the variable being a vector?

example

function(p):=p(1)*x+p(2)

with p being a vector

this gives me error

Thank you

Vectors are indexed starting at zero. To address the first element in a vector requires a subscript using the keystroke "[".

Your sheet then will look as:

I have made the function use both p (a vector) and x. You can put any vector (with at least two elements) into the function, and any value for x.

function(p):=p[1*x+p[2

Note however that the default origin of vectors in Mathcad is 0, not 1, so unless you change the default then

function(p):=p[0*x+p[1

If that doesn't work, please post the worksheet.
