Hello I want to simulate the below formulae in matlab with different vaalues of λ,T,S and P is it possible
Please let me know if it is possible to code and genrate differernt values of n with different values of λ,T,S and P open for any kind of suggetions or links that can be helpful
n=f( λ,T,S, P)
Thank You

Yes, you can write this in MATLAB. You will need to change λ to valid variable name
% random values
Lambda = 1;
T = 2;
S = 0.2;
P = 3;
n = 1.3247+3.3*10^3*Lambda^(-2)-3.2*10^7*Lambda^(-4)-2.5*10^(-6)*T^2+(5-2*10^(-2)*T)*(4* 10^(-5)*S)+(1.45* 10^(-5)*P)*(1.021-6* 10^(-4)*S)*(1-4.5* 10^(-3)*T)

Thank you so much for the reply I forgot to mention that the values I want to give them dyanamically and if I store the equation in variables of Lambda since it is not a perfect equation can I plot it ? Like some 3D view or something like that ?
