Statistics and Linear Algebra
DSP System Toolbox™ provides functionality for measuring streaming signal statistics such as mean, median, RMS, and peak-to-peak values in MATLAB® and Simulink®. You can perform several operations on these signals, such as adding the signal values along a specified dimension and converting the signal values into a dB scale.
DSP System Toolbox system linear algebra blocks enable you to work with matrices. For example, to solve a set of linear equations through Levinson-Durbin and Cholesky methods, use the Levinson-Durbin and Cholesky Solver blocks. These techniques are commonly used in applications such as the Yule-Walker AR problem and linear predictive coding. To factorize a square matrix into upper and lower components, use methods such as LDL factorization, LU factorization, and the QR factorization.
