% Allocate arrays for Celsius and Fahrenheit temperatures.

  tempC = zeros(2,1);
  tempF = zeros(2,1);

% Compute temperatures at graph end-points.

  tempC(1)  = -50; tempF(1)  = 9*tempC(1)/5 + 32;
  tempC(2)  = 100; tempF(2)  = 9*tempC(2)/5 + 32;

% Plot and label the graph

  plot( tempC, tempF );
