# Linear algebra matrix

Welcome to Linear Algebra. This course will cover Linear Equations, Matrix Algebra, Determinants, Vector Spaces, Eigenvalues and Eigenvectors, Orthogonality, and more! If you have any suggestions or would like more practice on a certain topic, please send your suggestions to [email protected] Lectures Linear Equations Systems of Equations and Matrix Notation Solving Systems of Equations By the invertible matrix theorem, if there is an n x n matrix D such that AD = I, then it must be true that there is also a n x n matrix C such that CA = I Given that all matrices are n x n If the columns of A are linearly independent, then the columns of A span R^n How to Diagonalize a Matrix. Step by Step Explanation. Determine Whether Each Set is a Basis for \$\R^3\$ Express a Vector as a Linear Combination of Other Vectors; How to Find a Basis for the Nullspace, Row Space, and Range of a Matrix; Prove that \$\{ 1 , 1 + x , (1 + x)^2 \}\$ is a Basis for the Vector Space of Polynomials of Degree \$2\$ or Less These six brief videos, recorded in 2020, contain ideas and suggestions from Professor Strang about the recommended order of topics in teaching and learning linear algebra. The first topic is called A New Way to Start Linear Algebra. The key point is to start right in with the columns of a matrix A and the multiplication Ax that combines those columns.That leads to The Column Space of a Matrix

Translation: this is a ``theoretical'' introduction to linear algebra, emphasizing abstract structures (vector spaces, linear transformations) as opposed to vectors and matrices. It's also intended to give you an introduction to writing mathematical proofs. Text: We will use the text Linear Algebra done right by Sheldon D. Axler.

In this course on Linear Algebra we look at what linear algebra is and how it relates to vectors and matrices. Then we look through what vectors and matrices are and how to work with them, including the knotty problem of eigenvalues and eigenvectors, and how to use these to solve problems. Matrices and Linear Algebra Introduction to Matrices and Linear Algebra Dot. The operator . Represents noncommutative multiplication and scalar product. When the operands are 1-column or 1-row matrices a and b, the expression a.B is equivalent to sum (a[i]*b[i], i, 1, length(a)).If a and b are not complex, this is the scalar product, also called the inner product or dot product, of a and b.

Let A denote the matrix   1 0 −2 0 5 0 −2 0 4   (a) (4 points) Find the eigenvalues of A. Answer: The characteristic polynomial of A is det   1− t 0 −2 0 5− t 0 −2 0 4−t   = (1− t)(5−t)(4− t)− (−2)(5−t)(−2) = (5− t)(t2−5t+4− 4) = −t(t − 5)2 Linear operator. By Marco Taboga, PhD. In linear algebra the term "linear operator" most commonly refers to linear maps (i.E., functions preserving vector addition and scalar multiplication) that have the added peculiarity of mapping a vector space into itself (i.E., ).The term may be used with a different meaning in other branches of mathematics.
