统计和线性代数
DSP System Toolbox™ 可用于在 MATLAB® 和 Simulink® 中测量流信号统计量，如均值、中位数、RMS 和峰间值。您可以对流信号执行多种操作，如沿指定维度添加信号值和将信号值转换为 dB 标度。
DSP System Toolbox 的线性代数模块使您能够处理矩阵。例如，要通过莱文森-杜宾和乔列斯基方法求解一组线性方程，请使用 Levinson-Durbin 和 Cholesky Solver 模块。这些方法通常用于尤尔-沃克 AR 问题和线性预测编码等应用中。要将一个方阵分解为上三角和下三角部分，请使用 LDL 分解、LU 分解和 QR 分解等方法。
精选示例
Streaming Signal Statistics
Perform statistical measurements on an input data stream using DSP System Toolbox™ functionality available at the MATLAB® command line. Compute the signal statistics minimum, maximum, mean, variance and peak-to-RMS and the signal power spectrum density and plot them.
Generate Standalone Executable and Interact with It Using UDP
Generate a standalone executable for streaming statistics using MATLAB® Coder™ and tune the generated executable using a user interface (UI) that is running in MATLAB®.
Remove High-Frequency Noise from Gyroscope Data
Remove high-frequency noise using a median filter.
Outlier Removal Techniques with ECG Signals
Explores different outlier removal filters and uses an electrocardiogram (ECG) signal as input.
