If you want to begin a modern subject in physics you encounter some mathematics concept, like matrices, for example in analytical mechanics or relativistic quantum mechanics we have matrices and we use Einstein summation convention, if you don't know this convention it would be impossible for you to start like those courses, but we have for you a solution! this course is specially designed for physics students or anyone want to start modern physics.

So in this course we have:

• Einstein summation convention

• Coupled equations and matrices

• Determinants

• Identity matrix

• Cofactors
