HBLG3_Matrix equations and systems of linear equations

The purpose of this learning graph is, on the one hand, to solve matrix equations and, on the other hand, to solve systems of linear equations, Matrices are the perfect tool for solving systems of equations. A very concise way of writing a system of linear equations is using the matrix equation: $A X = B$, where $A$ is an $n × m$ matrix, $X$ is an $m × 1$ matrix and $B$ is an $n × 1$ matrix.

Matrix operations

The purpose of this learning graph is, to work with matrix operations. Matrix operation mainly involves three algebraic operations which are addition of matrices, subtraction of matrices, and multiplication of matrices. We can also multiply a matrix by any constants, it is called scalar multiplication.

Elementary matrix operations, rank and inverse

Elementary matrix operations play a vital role in applications of algebra. It helps in solving linear equations in finding the inverse of a matrix and also finding the matrix rank. The three basic elementary operations or transformation of a matrix are: - Interchange of any two rows or two columns. - Multiplication of row or column by a non-zero number. - Multiplication of row or column by a non-zero number and add the result to the other row or column.
