I need help to make graphs please

Hello! I have the following program 1 that depends on subroutines 2,3 and 4 I need to graph [flux(index) vs w] and also [Q_t(j) vs d] can someone help me? The graphs should be on a logarithmic scale on both axes.

Answer 1

[Torsten]

See above. I added four lines to your code to plot the results and changed the line

flux(index)=fluxp+fluxe0+fluxe1+fluxe2;

to

flux(j,index)=fluxp+fluxe0+fluxe1+fluxe2;

Thnaks!

Answer 2

[Constantino Carlos Reyes-Aldasoro]

It is easier to help for specific questions, i.e., you tried something and it did not work. The way you have phrased this is more like trying to solve your homework and you will not get much help.

[Yordani]

OK thank you!
