Syntax

displayfeasiblesolutions(solution)

Description

displayfeasiblesolutions(solution) displays all feasible solutions found during the approximation process, including the best solution. Feasible solutions are defined as any solutions to the original FunctionApproximation.Problem object that met the constraints defined in the associated FunctionApproximation.Options object.

Input Arguments

expand all

FunctionApproximation.LUTSolution object from which to display all associated feasible solutions.

Examples

Create a FunctionApproximation.Problem object defining a math function to approximate. 

problem = FunctionApproximation.Problem('sin')
problem = 
  1×1 FunctionApproximation.Problem with properties:

    FunctionToApproximate: @(x)sin(x)
           NumberOfInputs: 1
          NumberOfOutputs: 1
               InputTypes: "numerictype(0,16,13)"
         InputLowerBounds: 0
         InputUpperBounds: 6.2832
               OutputType: "numerictype(1,16,14)"
                  Options: [1×1 FunctionApproximation.Options]

Use the solve method to get a FunctionApproximation.LUTSolution object.
