Hello need help. I have a problem these questions. I need MATHLAB's solution. Thank You ! (Using with MATHLAB)

Example 1: Sum all elements of a vector using for loop; (15p) A [7 14 4 2 12 5 0 1] Example 2: In this example we will simply find the factorial of a number which we will request from the user. More explicitly, we want the mini program to ask a number from a user, verify that the number is not negative, and compute its factorial. (15p) Example 3: Draw the graph of functions below; zexp(-0.5t) cos(20t -6) for 0st 8 (5p) Sin t for 0 t 10 (5p) Example 4: Write the MATLAB code that produces a simple plot for the waveform defined as; (15p) -4t -3t Example 5: Suppose we would like to define and plot the piecewise defined function. (15p) -1
