Image Rotation
I used the size() function to determine the size of the input file's picture's matrix, and then used the inverse transformation matrix shown below to determine the source pixel for each destination pixel. My program determined whether the source pixel was within the 320 x 200 dimensions, and if so, painted the destination pixel into the output file and if not, left the value as 0, i.e. black.

…showed last 75 words of 264 total…and width than the original due to the fact that Outhorizontal and Outvertical needed the input of the current pixel and the adjacent pixel on the right, and the rightmost pixel was excluded.
Image Blurring
By averaging the pixel values with the 8 surrounding pixels, a blurring effect was achieved. Using the blurring formula shown below, blur.m processes all the pixels and creates a matrix "sum" which is a 'shifted' version of the original image.
