T is one to one.Note that both functions we obtained from matrices above were linear transformations. Let's take the function f(x, y) = (2x + y, y, x − 3y) f ( x, y) = ( 2 x + y, y, x − 3 y), which is a linear transformation from R2 R 2 to R3 R 3. The matrix A A associated with f f will be a 3 × 2 3 × 2 matrix, which we'll write as.

Dilation. Dilation is a process of changing the size of an object or shape by decreasing or increasing its dimensions by some scaling factors. For example, a circle with radius 10 unit is reduced to a circle of radius 5 unit. The application of this method is used in photography, arts and crafts, to create logos, etc.Shear transformations are invertible, and are important in general because they are examples which can not be diagonalized. Scaling transformations 2 A = " 2 0 0 2 # A = " 1/2 0 0 1/2 # One can also look at transformations which scale x differently then y and where A is a diagonal matrix.
