Matrix transformations | Linear algebra | Math | Khan Academy
Matrices can be used to perform a wide variety of transformations on data, which makes them powerful tools in many real-world applications. For example, matrices are often used in computer graphics to rotate, scale, and translate images and vectors.
Visualizing linear transformations (article) | خان اکیڈیمی
A really nice way to describe all this is to represent a given linear transform with the matrix below: A = [ a b c d ] In this matrix, the first column tells us where [ 1 0 ] lands, and the second column tells us where [ 0 1 ] lands.
Matrix transformations | Linear algebra | Math | خان اکیڈیمی
For example, matrices are often used in computer graphics to rotate, scale, and translate images and vectors. They can also be used to solve equations that have multiple unknown variables (x, y, z, and more) and they do it very efficiently!
Compositions of linear transformations 1 (video) | Khan Academy
The next video, now that we know this is a linear transformation, and that we know that we can represent it as a matrix vector product. We'll actually figure out how to represent this matrix, especially in relation to the two matrices that define our transformations, S and T.
