Hi There!
I'd like to plot the following function with matlab as a theta function
but the graphs looks completely wrong.
What should I do?

What should you do? You should correct whatever mistake it is you made.

There are no code mistakes. Simply the graph is not the one I expect...
Here is what I typed in:
x = linspace(0,2*pi,100);
y = ((1-exp(-1.9./cos(x)))./(1-exp(-1.9))).*cos(x);
