Class Solver

constructor

• new Solver(exprs, initial): Solver

• Parameters

  • exprs: Expr[]

    List expressions to solve for
  • initial: VarMap

    A map of variables to their corresponding initial value as a number

  Returns Solver

exprs

Readonly jacobian

Readonly vars

convergeToRMSE

• convergeToRMSE(error, maxIterations?): void

• Iterate the solver until RMSE of expressions gets to or under specified error number; Or leave when reached number of iterations specified by maxIterations.
  Note: Use if the solver converges quickly, as calculating RMSE can be expensive.

  Parameters

  • error: number
  • Optional maxIterations: number = -1

    Maximum number of iterations. Use -1 (default value) to iterate without any limit

  Returns void

getRMSE

• getRMSE(): number

• Get root mean square error by determining how far solver's expressions are from zero using current values and state of solver.

  Returns number

iterate

• iterate(): void

• Iterate the solver once

  Returns void

var_map

• var_map(): Map<Variable, number>

• A map of variables to their current values.
  This values will change and become accurate by iterating the solver

  Returns Map<Variable, number>
