StepFunction(double[] x,
double[] y)
Builds a step function from a list of arguments and the corresponding
values.

h(x) = y[0] for all x < x[1]

x[0] is ignored, but it must be strictly less than
x[1].x - Domain values where the function changes value.y - Values of the function.NonMonotonicSequenceException - if the x array is not sorted in strictly increasing order.NullArgumentException - if x or y are null.NoDataException - if x or y are zero-length.DimensionMismatchException - if x and y do not
have the same length.public double value(double x)
