Matlab code to descramble an image using the following steps?

• Create a blank image of the same size as the image puzzle
• Go to every row and column location in the image and do the following:– Move the current pixel to a new row and column location in the blank image:
• If at an even col index, use the formula: newColumn = column/2
• If at an odd col index, use the formula: newColumn = (column + 1)/2 +imageWidth/2
• If at an a row in top half of image, use the formula: newRow = imageHeight/2 +1 − row
• If at an a row in bottom half of image, use the formula: newRow = 3 ∗imageHeight/2 + 1 − row
