my programm is actually just a simple backlash problem.
Vlmin = [0.0756;0.102;0.1404;0.1848;ect]
p_in = [50.855994816125985;56.758823881954406;64.706344253059480;72.994646508377330; ect]
b = (deltap-deltap_lambda-deltap_zetaT)*(2/dichte);
A = zeros(m,4);
for i = 1:m
A(i,1) = (V(i)/A2)^2;
A(i,2) = (V(i)/A1)^2;
A(i,3) = (V(i)/A3)^2;
A(i,4) = (V(i)/A5)^2;
end
C = A.'*A;
D = A.'*b;
x = C\D;
When I run it , I get the notification "Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 1.699518e-25.". do you know how I can solve this issue..
I m welcomed to every idea
