Rotate 90 degrees clockwise pdf#

I have also made a video on the same topic. I hope you have understood both these programs with logic. This program will rotate the matrix in an anti-clockwise direction by 90 degrees. Matrix Rotation in C By 90 Degree Clockwise #include Īlso Read: Reverse a Number using getchar and putchar function in c Matrix Rotation in C By 90 Degree Anti-Clockwise #include Īlso Read: C Program to Print Numbers Except Multiples of n Here, I have written two separate c programs for matrix rotation i.e. In this article, we have explored an efficient way to Rotate Image: matrix of size NxN by 90 degrees (clockwise) inplace by using a property of XOR. I recommend you to learn arrays in c programming for understanding this program.Īlso Read: C Program to Remove Zeros from a number

When we rotate the original matrix by 90 degrees anti-clockwise, then the last column of the original matrix becomes the first row of the output matrix and the first number of the last column of the original matrix becomes the first number of the first row of the matrix and so on.

When we rotate the original matrix by 90 degrees clockwise, then the first column of the original matrix becomes the first row of the output matrix and the last number of the first column of the original matrix becomes the first number of the first row of the matrix and so on.

The logic for the cdf of a rotated copula is quite similar.

Rotate 90 degrees clockwise pdf#

The same procedure also works for 180 and 270 degrees: To sum up, the following formulas for pdf values of clockwise rotated copulas hold: cdf. Hence, we get the pdf value of a clockwise 90° rotated copula with. We know that matrix is made up of rows and columns only. Whenever I compress an image taken straight from the camera (in portrait mode) the image gets rotated 90 degrees counter-clockwise after compressed. Going from the left to the right figure, the rotation has been reverted. Now, I am going to tell you the logic of this program of matrix rotation in c. anti-clockwise.Īlso Read: C Program to Print Multiples of 5 using do while loop Have you observed any change in both the diagrams? In the second figure, we are rotating the matrix to the left side from the right side i.e. Matrix Rotation in C – 90 Degrees Anti- Clockwise Matrix Rotation in C 90 Degrees Anti-Clockwise Similarly, we are going to rotate the same matrix by 90 degrees anticlockwise. Matrix Rotation in C 90 Degrees Clockwise

In simple words, we can say that we are rotating the matrix from left to right. You can see how this matrix will look like after rotating about 90 degrees clockwise. In the following diagram, we are rotating the 3*3 matrix by 90 degrees clockwise. Before writing the c program for this, let us see the following figures.Īlso Read: Switch Case in C Program to Calculate Area of Circle and Triangle Matrix Rotation in C – 90 Degrees Clockwise In this program, we will rotate the matrix by 90 degrees to both sides i.e. You can use this rule to rotate a pre-image by taking the points of each vertex, translating them according to the rule, and drawing the image. In this post, I am going to write a program for matrix rotation in c. The general rule for rotation of an object 90 degrees is (x, y) > (-y, x).
