Plot 3 with data set and one equation
显示 更早的评论
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,

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);
