Matrix is an arrangement of numbers into rows and columns. Make your first introduction with matrices and learn about their dimensions and elements.

The dimensions of a matrix tell the number of rows and columns of the matrix in that order. Since matrix A has 2 rows and 3 columns, it is called a 2 × 3 matrix.

Sal discusses the conditions of matrix dimensions for which addition or multiplication are defined.

This topic covers: - Adding & subtracting matrices - Multiplying matrices by scalars - Multiplying matrices - Representing & solving linear systems with matrices - Matrix inverses - Matrix …

Intro to determinant notation and computation Interpreting determinants in terms of area Finding area of figure after transformation using determinant Proof: Matrix determinant gives area of …

The Hessian is a matrix that organizes all the second partial derivatives of a function.

What I want to do in this video is explore the notion of a matrix outside of the context of a surprisingly good movie that involves Keanu Reeves. And it's actually the first of three.

Most animal cells release materials into the extracellular space, creating a complex meshwork of proteins and carbohydrates called the extracellular matrix (ECM).

A graph represents a single function, from x onto y. A matrix holds a lot more information than that. Matrices perform transformations on the entire space they act upon, so I'm not …

What I'm going to do in this video is introduce you to a new type of space that can be defined around a matrix, it's called a column space. And you could probably guess what it means just …
