What is a Matrix?

A matrix is a rectangular array of numbers arranged in rows and columns. It is widely used in linear algebra to represent data and solve systems of equations.

Types of Matrices

• Row Matrix
• Column Matrix
• Square Matrix
• Identity Matrix
• Zero Matrix

Matrix Addition

Matrix addition is performed by adding corresponding elements of two matrices of the same size.

Formula:

C = A + B

Matrix Subtraction

Matrix subtraction works similarly to addition but subtracts corresponding elements.

Matrix Multiplication

Matrix multiplication is possible only when the number of columns in the first matrix equals the number of rows in the second matrix.

Formula:

C[i][j] = Σ (A[i][k] * B[k][j])

Applications of Matrix

• Engineering calculations
• Computer graphics
• Data science
• Physics equations
• Machine learning

Step-by-Step Example

Matrix A = [1 2; 3 4] Matrix B = [5 6; 7 8]

Addition Result = [6 8; 10 12]
