I have a vector of function F=(F1,F2…Fn) and F1 contains n variables (x1,x2...,xn), Same for F2 to Fn. I want to evaluate F by a vector x, How can write it using JavaScript?
F and x are vectors.
F=[[F1],[F2]…[Fn]];
x=[[x1],[x2]…[xn]];
I want to return
y = [[F1(x)],[F1(x)]…[Fn(x)]]
For example:
F=[[x1^2 - x2 -1], [x1 - x2^2 + 1]]
x=[[1], [2]]
It's hard to tell exactly what you're looking for from your question, but I thought I would give a shot at giving you an answer.
The first thing I do, is describe an array where each element is a function. Then I create an array of values to pass to each function. Finally, I use the Array .map method to pass the values into each function and give the result in a results array.
const functions = [
(x1, x2) => x1 ** 2 - x2 - 2,
(x1, x2) => x1 - x2 ** 2 + 1
];
const xVals = [1, 2];
const results = functions.map(fn => fn(...xVals));
console.log(results); //logs [-3, -2]
