From this page you can access a collection of materials dealing with some important areas of Linear Algebra. For Maynooth University students, this material is typically covered in parts of Linear Algebra 2 (MT211S and MT212A). For more resources on preliminary topics see **Introduction to Linear Algebra**. These resources are not a replacement for the material covered in your lectures and assignments, rather you should use them as extra support to aid your understanding of any material you may have difficulties with.
