This video introduces my course on Matrix Algebra which covers various topics to solve a system of equations such as:
Rank of a matrix using the echelon and normal form
Guess Elimination method and Gauss Jordan method
Gauss Siedel Iterative method
Inverse of a matrix using adjoint.
As a bonus, I have provided all the formulae taught in this course in a single video. There is also an assignment/project at the end.
