Study Notes
Linear Algebra - BAS113
- Course instructors are Dr. Amira A. Allam and Dr. Mahmoud Owais
- Course is titled Linear Algebra, BAS113
- Course is taught at Sphinx University
- Lecture 3 focuses on Matrix Operations 2
Matrix Operations
- Elementary Row Operations
- Interchange two rows
- Multiply a row by a non-zero constant
- Replace a row with the sum of itself and a constant multiple of another row
- Row-Equivalent Matrices
- Two matrices A and B are row-equivalent (A ~ B) if one matrix can be obtained from the other by a finite number of elementary row operations.
Row-Echelon Form
- A matrix is in row-echelon form if:
- The first nonzero entry (leading entry) in each row is 1
- All entries below the leading entry in a column are zeros.
- Leading entries must occur further to the right in successive rows.
Reduced Row-Echelon Form
- A matrix is in reduced row-echelon form if:
- It's in row-echelon form.
- The leading entry of each row equals 1
- Every column containing a leading 1 has zeros elsewhere in the column.
Inverse of a Matrix
- A matrix A is invertible (or nonsingular) if there exists a matrix B such that AB = BA = I (the identity matrix).
- If B is the inverse of A, it is denoted as A⁻¹.
- Finding the inverse of a given matrix often involves row operations to transform the matrix into the identity matrix and record the same operations in a parallel column representing the inverse matrix.
