Introduction to MATLAB Vectors and Matrix
A Professional Interactive Report & Web Demonstration
1. Introduction to a Row Vector
In MATLAB, a row vector is a 1D array of numbers arranged horizontally. It is essentially a matrix with one row and multiple columns. Elements are separated by spaces or commas.
Syntax: v = [1, 2, 3, 4]

2. Introduction to a Column Vector
A column vector is a 1D array arranged vertically, representing a matrix with multiple rows and a single column. In MATLAB, elements are separated by semicolons (;).
Syntax: v = [1; 2; 3; 4]
Interactive Vector Transpose
Click the button to transpose the row vector into a column vector.
3. What is Line Spacing (linspace)
The linspace function generates linearly spaced vectors. It is highly useful for creating points for plotting or generating coordinate arrays.
Syntax: linspace(start_value, end_value, number_of_points)
linspace(0, 10, 5)
4. Concept of Indexing
Indexing in MATLAB allows you to extract or modify specific elements in an array or matrix using their row and column coordinates. MATLAB uses 1-based indexing.
Syntax: A(row, column)
Interactive Indexing Grid
Click any cell to see its MATLAB index.
A(?, ?) = ?
5. Concept of Logical Indexing
Logical indexing provides a fast way to filter data. By applying a logical condition, MATLAB creates a binary mask (array of 1s and 0s) to extract elements that meet the criteria.
Syntax: A(A > 5)
Highlight Values > 5
6. Introduction to Matrices
A matrix is a two-dimensional rectangular array of numbers. MATLAB is specifically optimized for matrix operations (MATLAB stands for Matrix Laboratory).
Syntax: A = [1, 2; 3, 4] creates a 2×2 matrix.
7. Matrix Addition and Subtraction
Matrices must have the exact same dimensions to be added or subtracted. The operations are performed element-wise.
