Hi @Nudrat Sufiyan
Guess you need to type out this equation
and insert the parameters
Example only, not true equation. One of the simpler way without using loop.
% code that you have typed so far
T = linspace(300, 600, 30001);
a = 2.61e-4;
b = 2.90e-4;
c = 1.70e-2;
kc = 0.3;
theta = 1065;
Nd = 10e16;
Ni = (1 + kc)*Nd;
% additional stuffs that you should type
beta = 1; % a bit lazy to type out, trying doing it yourself
iMu = a*(Ni/1e17)*log(1 + beta.^2).*(T/300).^(-1.5) + b*(T/300).^(1.5) + c./(exp(theta./T) - 1);
plot(T, 1./iMu), hold on
% copy/paste and modify the value of Nd
Nd = 10e17;
iMu = a*(Ni/1e17)*log(1 + beta.^2).*(T/300).^(-1.5) + b*(T/300).^(1.5) + c./(exp(theta./T) - 1);
plot(T, 1./iMu)
Nd = 10e18;
iMu = a*(Ni/1e17)*log(1 + beta.^2).*(T/300).^(-1.5) + b*(T/300).^(1.5) + c./(exp(theta./T) - 1);
plot(T, 1./iMu), hold off, grid on, xlabel('T, [K]'), ylabel('\mu, [put the unit here]')
