Matlab Problems

Problem 1. Create a simple plot of hyperbolic secant function (sech) using the exponential function, or similar, with axis labels and a title using a script. Put the script and the plot into a word processed file.

Problem 2. Create the table in a small script. Use a diary file to display the script by typing "diary <filename>" at the prompt, then "type <plotfile>.m", then executing the file. Typing "diary" at the prompt will then stop recording what happens at the prompt. Feel free to copy the diary file into a word processed file.

Problem 1
x = -2*pi:0.01:2*pi;
y=2./(exp(x)+exp(-x));
plot(x,y);
xlabel('x');
ylabel('y');
title('Graph of the hyperbolic secant');...
