Define the following matrix "array1" and display the contents of the following subarrays: array1 1.1 0.0 2.1 -1.4 0.0 -2.1 -3.5 -3.0-5.6 2.8 0.3 0.1 -0.4 5.1 0.0 1.1 -3.0 6.0 4.3 1.3 1. Extract the third row from the matrix "array1", 2. Extract the second column from the matrix "array 1". 3. Extract a submatrix "array2" that contains three rows and two columns from the matrix "arrayl" 4. Find the size of the matrix "array!". 5. Replace the number 1.1 in the matrix "array!" with 2.2. 6. Transpose the matrix "array2". 7. Sum the element at each column in the matrix "array!". 8. Sum the element at each row in the matrix "array 1". 9. Find the sum of all element in "array1". 10. Find the elements at the diagonal using: diag(array1) 11. Flip the matrix from left to right using: fliplr(array 1 Q2: Write a matlab code that can load a gray scale medical image and do the following: 1. Read the image and show it in MATLAB. 2. Find the maximum and minimum intensities in the image (use max, and min commands) 3. Find the intensity at the origin. 4. Show the color map at the right side of the image (intensity levels). 5. Find the size of the image (number of rows and columns). 6. What are the intensity values of the pixels at the coordinates: (2,10), (190,120) and (100,220)? 7. Define the location of a small object in the image and then extract it to be a new image. 8. Show the extracted part of the image as a new image. 9. Calculate the number of bits of each image. 10. How many bits need to store the image in the computer?
