Question

Section 2: Building step and ramp functions in Matlab The following function applies the unit step function to each element of an input vector x. Copy and save this file as u.m in the default workspace and then create the graph of the unit step function using the directions provided.

function y = u(x)

for n = 1: length(x)

if (x(n) < 0) y(n) = 0;

else y(n) = 1;

end

end

end

Testing the function:

Explanation / Answer

for i=1:20
      x(i) = i-10;
      y(i) = x(i) ^ 2;
    end

    % Plot the X values vs. the Y values
    plot(x,y);

    % Label the plot
    xlabel('X axis');
    ylabel('Y axis');
    title('Graph of X^2');
    legend ('X squared');
    grid on;
