How to plot complicated exponential function 4.82 (1 + 0.35 e^ −4.07t ) / (1 − 0.35 e^−4.07t) on matlab

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)

Answer 1

[Mathieu NOE]

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));
