I need help plotting the function above in MATLAB. Currently an empty graph shows up when I tried to set the x and y values and plot the graph and I can't figure out what's wrong with my code:
x = 0 : 0.01 : 10.00;
y = ((4.8184) * (1 + 0.3497.*exp(-4.0719.*x))) / (1 - 0.3497.*exp(-4.0719.*x));
plot(x, y)

your y output is a scalar because your division is / and not ./
so this works :
x = 0 : 0.01 : 10.00;
y = ((4.8184) * (1 + 0.3497.*exp(-4.0719.*x))) ./ (1 - 0.3497.*exp(-4.0719.*x));
plot(x, y)

Use the element-wise division when computing y:
y = ((4.8184) * (1 + 0.3497.*exp(-4.0719.*x))) ./ (1 - 0.3497.*exp(-4.0719.*x));
