Explain the instruction ( fliplr) with example? Your answer

The Correct Answer and Explanation is:

The instruction fliplr stands for “flip left to right” and is commonly used in programming, especially in MATLAB and other languages like Python, to reverse the elements of an array or matrix along the horizontal axis (left to right). When applied, it flips the order of columns but keeps the rows intact.

Example:

Consider the following matrix:

tA = [1 2 3 4;
     5 6 7 8];

Here, the matrix A has two rows and four columns. If we apply fliplr(A), the matrix will be flipped horizontally, and the result will look like:

fliplr(A) = [4 3 2 1;
             8 7 6 5];

Explanation:

• Before flipping: The first row of matrix A is [1 2 3 4], and the second row is [5 6 7 8].
• After applying fliplr: The columns are reversed for each row, so the first row becomes [4 3 2 1], and the second row becomes [8 7 6 5].
• The rows remain unchanged, only the order of the columns has been flipped.

In general, this operation is used when you want to reverse the elements of an array or matrix along the horizontal axis but do not want to change the order of the rows. It is especially useful in data manipulation and image processing when you need to mirror or flip the data horizontally.

For example, in image processing, flipping an image left to right creates a mirror image, which can be useful for certain transformations or effects.

Code Example in MATLAB:

= [1 2 3 4; 5 6 7 8];
B = fliplr(A);
disp(B);

This code will produce:

iniCopyEditB = [4 3 2 1; 8 7 6 5];

It flips the columns of matrix A left to right and stores the result in matrix B
