Yes William, Your code works for me as well. I get a neat plot
displayed as yours. Here the software chosen is sage.
My question is:
Is it not possible to write a simple matlab code as I wrote before and
select the option Matlab instead of sage in the list of softwares
available and have it working?
It does all the math and displays the result but not the plot.
