XAtYMin

X value at the index where Y is minimum.

Syntax

M = XAtYMin(X, Y)

Description

Given paired samples X and Y of the same length, returns the value of X at the index where Y is minimum. Useful for locating where a signal reaches its low point.

MathJet-specific (not in MATLAB).

Examples

x = 1:5; y = [3 1 5 2 4];
XAtYMin(x, y)            % 2  (Y is min at index 2 → X(2))

• YAtXMin — Y value at the index where X is minimum.
• XAtYMax — X value at the index where Y is maximum.
• min — Minimum value along a dimension, or elementwise minimum of two inputs.
