This course covers fundamental understanding and solution to a system of linear equations, Ax=b, which appears in many engineering problems. The course also deals with the condition when Ax=b has many or no solutions.

The last topic of this course Is to deal with the condition when b does not lie on the columns space of A. Hence, It Is needed the notion of projection of vector b on the column space of A. The method of least square will serve as an example of this condition.
