ezplot tanh(x) from -2pi to 2pi in matlab

To ezplot tanh(x) from -2pi to 2pi in Matlab, you can follow these steps:

1. Define the function tanh(x) using the symbolic toolbox in Matlab.
2. Use the ezplot function to plot the graph of tanh(x).
3. Set the range from -2pi to 2pi.
4. Add labels and title to the plot for better visualization.

Here's the code to do that:

main.m
syms x
tanh_function = tanh(x);
ezplot(tanh_function,[-2*pi, 2*pi]);
title('Plot of tanh(x)');
xlabel('x');
ylabel('tanh(x)');
