Скачать или смотреть MATLAB Logical Indexing Explained: Chapter 4 Beginner's Guide

This video explains the concept of logical indexing in MATLAB, showing how to efficiently select and manipulate elements of vectors based on specified logical conditions. Through practical MATLAB examples, it demonstrates how logical vectors are created and used to extract desired data without explicit loops, significantly simplifying data filtering and analysis.

Key Highlights
Introduces logical indexing, where a logical (Boolean) array is used to select elements of another vector based on a condition (such as values greater than 50).

Details how MATLAB comparisons (e.g., A greater than 50) return logical arrays, which, when used as indices, filter out unwanted elements in a single line of code.

Shows combining multiple conditions (e.g., values greater than 50 and less than 80) for more complex filtering using logical operators.

Highlights the efficiency and brevity of logical indexing, significantly reducing code complexity compared to explicit for-loops, and discusses how output vector sizes change after filtering.

This tutorial is ideal for anyone learning MATLAB who wants to master powerful methods for data selection and vectorized programming using logical indices.
