This lesson covers the different types of inverses of matrices, including left and right inverses and pseudo-inverses. The instructor explains the cases where a matrix has a perfect inverse, a left inverse or a right inverse, and the corresponding null spaces for each case. The pseudo-inverse is introduced as a more general type of inverse for matrices that don't fit into the previous categories. Overall, the lesson provides a comprehensive overview of matrix inverses and their properties.
Left and Right Inverses and Pseudo-Inverses -- Lecture 33. Learn about different types of inverses of matrices.
