Many university STEM major programs have reduced the credit hours for a course in Matrix Algebra or have simply dropped the course from their curriculum. The content of Matrix Algebra in many cases is taught just in time where needed. This approach can leave a student with many conceptual holes in the required knowledge of matrix algebra.
In this series of blogs, we bring to you ten topics that are of immediate and intermediate interest for Matrix Algebra.
Here is the

ninth topic where we talk about the adequacy of solutions of simultaneous linear equations. Learn how this adequacy is measured through the condition number of the coefficient matrix, and how the condition number is calculated approximately as well. Get all the resources in form of textbook content, lecture videos, multiple choice test, problem set, and PowerPoint presentation.
