Struct xxcalc::linear_solver::LinearSolver
[−]
[src]
pub struct LinearSolver;
LinearSolver is a calculator using a LinearSolverParser and a LinearSolverEvaluator,
to provide multiple arithmetic operations and basic linear solver capability.
The solver support the same operators as a PolynomialCalculator, but it adds
= operator which tries to solve value of x and returns it.
While usage of the solver is the easiest way of embedding solving engine into
your program, please note that a Tokenizer, LinearSolverParser and LinearSolverEvaluator
is created with each call, which requires reallocation of memory.
Examples
assert_eq!(LinearSolver.process("2 * x + 0.5 = 1"), Ok(Polynomial::constant(0.25))); assert_eq!(LinearSolver.process("2x + 1 = 2(1-x)"), Ok(Polynomial::constant(0.25))); assert_eq!(LinearSolver.process("x^2-x^2+x=2"), Ok(Polynomial::constant(2.0))); assert_eq!(LinearSolver.process("1-x=x"), Ok(Polynomial::constant(0.5)));Run
