Multiplication Of Matrices Numerical
 
03:22
Multiplication Of Matrices In mathematics, matrix multiplication is the operation of multiplying a matrix with either a scalar or another matrix. This article gives an overview of the various types of matrix multiplication. he ordinary matrix product is the most often used and the most important way to multiply matrices. It is defined between two matrices only if the width of the first matrix equals the height of the second matrix. Multiplying an m×n matrix with an n×p matrix results in an m×p matrix. If many matrices are multiplied together, and their dimensions are written in a list in order, e.g. m×n, n×p, p×q, q×r, the size of the result is given by the first and the last numbers (m×r), and the values surrounding each comma must match for the result to be defined. The ordinary matrix product is not commutative. The element x3,4 of the above matrix product is computed as follows The first coordinate in matrix notation denotes the row and the second the column; this order is used both in indexing and in giving the dimensions. The element at the intersection of row i and column j of the product matrix is the dot product (or scalar product) of row i of the first matrix and column j of the second matrix. This explains why the width and the height of the matrices being multiplied must match: otherwise the dot product is not defined. The figure to the right illustrates the product of two matrices A and B, showing how each intersection in the product matrix corresponds to a row of A and a column of B. The size of the output matrix is always the largest possible, i.e. for each row of A and for each column of B there are always corresponding intersections in the product matrix. The product matrix AB consists of all combinations of dot products of rows of A and columns of B.

Dot Product 3x1 and 2x2 matrix. Cross Product 3x1 matrix
 
09:34
In this video it is explained how to calculate the dot product of 3x1 and 2x2 matrix. Secondaly it is also explained how to find out cross product of 3x1 matrix. In order to find the dot product we just need to multiply first number with first, second with second and third with 3 number. It must be kept in mind in order to do dot product calculation we need A and B (two) matrix. This operation is not possible with one matrix. Secondaly in the video it is explained how to calculate the Cross product of 2x2 matrix. In my next videos I shell explain further in more detalis things like 3x3 matrix cross product.

Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more.

Linear Algebra Example Problems - The Matrix Product Ax
 
06:20
http://adampanagos.org This video provides several different examples of computing the matrix-vector product Ax where A is a matrix and x is a vector. This product is only defined when the number of columns in A equals the number of rows in x. When this is the case, the product Ax is defined as a linear combination of the columns of A where each column is weighted by the entries of the vector x.
