Purpose
Calculate Root Mean Square Difference(Error).
Synopsis
- err = rmse(y1,y2)
Description
RMSE is used to calculate the root mean square difference between two vectors or matrices. If the vector or matrix is from a model estimation and measurements then the output is the Root Mean Square Error (RMSE). Output depends on the input: A) y1 is a matrix or vector
err = rmse(y1);
The output err is the root mean square of the elements of y1. B) y1 is a matrix or vector, y2 the same size as y1
err = rmse(y1,y2);
The output err is the root mean square of the difference between y1 and y2. C) y1 is a matrix or vector, y2 a column vector.
err = rmse(y1,y2);
The output err is the root mean square of the difference between each column of y1 and y2. For example, y2 is a reference and the RMSE is calculated between each column of y1 and the vector y2.
