Dear all.
I have data set for EQ and lamda, and I have one equations about C.
I would like to make a figure using plot3 or surf. Please let me know how to to it.
Thank you very much in advance.
Sincerely yours,

EQ lamda
0.7835 0.118
0.7939 0.115
0.8043 0.1121
0.8148 0.1093
0.8254 0.1066
0.8360 0.104
0.8468 0.1014
0.8577 0.0989
0.8687 0.1347
0.8799 0.1195
0.8911 0.1066
0.9024 0.0845
ep = 1;
gam1 = 0.3;
eta11 = 0.001;
eta21 = 0.003;
A = gam1+gam1*eta11-1;
C = (ep*eta11)^((gam1*eta11)/A)*EQ.^((-gam1*eta21)/A)*lamda.^(1/A);
Plot3(EQ,lamda, C);
Surf(EQ, lamda, C);

Dear KSSV,
Thank you very much for your answer..
I tried to make a figure, and I found that C value are the same, there is no change at all.
I would like to fix this problem. I deeply appreciate your help again.
Sincerely yours,
J1
