/**
* Parse and compile an expression.
* Returns a an object with a function `evaluate([scope])` to evaluate the
* compiled expression.
*
* Syntax:
*
* math.compile(expr) // returns one node
* math.compile([expr1, expr2, expr3, ...]) // returns an array with nodes
*
* Examples:
*
* const code1 = math.compile('sqrt(3^2 + 4^2)')
* code1.evaluate() // 5
*
* let scope = {a: 3, b: 4}
* const code2 = math.compile('a * b') // 12
* code2.evaluate(scope) // 12
* scope.a = 5
* code2.evaluate(scope) // 20
*
* const nodes = math.compile(['a = 3', 'b = 4', 'a * b'])
* nodes[2].evaluate() // 12
*
* See also:
*
* parse, evaluate
*
* @param {string | string[] | Array | Matrix} expr
* The expression to be compiled
* @return {{evaluate: Function} | Array.<{evaluate: Function}>} code
* An object with the compiled expression
* @throws {Error}
