显示在查找表逼近期间找到的所有解

创建一个 FunctionApproximation.Problem 对象，用于定义要逼近的数学函数。然后，使用 solve 方法获取一个 FunctionApproximation.LUTSolution 对象。

使用 displayallsolutions 方法显示在逼近过程中找到的所有解。

problem = FunctionApproximation.Problem('sin')

problem = 

  FunctionApproximation.Problem with properties

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

solution = solve(problem)

solution = 

  FunctionApproximation.LUTSolution with properties
