Purpose
Finds the index of the array element closest to chosen value.
Synopsis
- index = findindx(array,r)
Description
Inputs are an array of values array and a value to locate r. Output index is the linear index into array which will return the closest value to r.
Inputs
- array = input data array.
- r = target value.
Outputs
- index = linear index into array that returns the closest value to r.
Examples
index = findindx(array,r); %get an index nearest_value = array(index); %find the value
