Threshold 1D Array

Description

Interpolates points in a one-dimentional array that represents a two-dimentional non-descending graph. This function compares threshold y to the values in array of numbers or points starting at start index until it finds a pair of consecutive elements such that threshold y is greater than or equal to the value of the first element and less than or equal to the value of the second element.

Input parameters

array of numbers or points : class, a one-dimentional tensor of numbers or a tensor of points where each point is a cluster of x- and y-coordinates. If this input is an tensor of points, this function uses the second elements in the clusters, or the y-coordinates, to obtain a fractional index that it then uses to interpolate the corresponding x value.
threshold y : float, threshold value for the function. If threshold y is less than or equal to the array value at start index, the function returns start index for fractional index or x. If threshold y is greater than every value in the array, the function returns the index of the last value.
start index : integer, must be a number. The default is 0, which means the function returns the result calculated from the entire array, rather than a specified section of the array.

Output parameters

fractional index or x : float, interpolated result function calculates for the array of numbers or points one-dimentional input tensor.
