The Matlab proposition

  1. Simulate (use Simulink, draw the water level in the pound lock after valve opening):

  1. Read the attached file and plot a graph. Color cyan, dashed. Add title "Signal".
  2. Using matrix multiplication and inversion or the left division, solve:
    5 x -3 y +   z = 5
    -4 x  +3 y  +2 z  =  9
    6 x -7 y +3 z = 3

    Test the result.
