How to draw this graph using matlab code ignore the labeling

[Harry]

Dear Kalyan Acharjya,

I need matlab code to plot this graph.Thank you for your help

Answer 1

[KALYAN ACHARJYA]

t=1:.1:8;
y=log(t);
y(t>5)=0;
plot(t,y,'b','linewidth',1);
set(gca,'YTickLabel',[]);
xlabel('Energy');
ylabel('D(E)'); %You can insert signma also, try it

MVPs, I don't know what I am doing..I have no clue. Is there any sense to producing the graph like this? From the labels, it seems the plots related to statistical mechanics /quantum mechanics.

yes sir, it is quantum mechanics work. I dont know how to use matlab but my lecturer ask me to plot graph using it. how do i plot this then? adding another red line graph on it

[KALYAN ACHARJYA]

Hey, read the literature (Energy vs density of states), there may be relation between energy and density of states (D), May be when T>0, the graph behave as red line.

D(E)= Function of (Energy,T, and other terms etc)

Define E (Energy) and all other terms

Calculate D(E) with respect to different values of E

plot(E,D_E)

Discuss with your teacher, regarding Mathematical expression and typical values of all other terms. If you do that, the plot implementation on Matlab, hardly takes 5-10 min.

Is this related to this one, not sure

Good Wishes! Keep Learning!

Find a similar plot at the MATLAB Plot Gallery, copy the code from there, and adapt it to your case.
