Function not using given Variables
显示 更早的评论
I'm trying to solve a system of 6 non linear equations using Newton Raphson Method. I defined my equations with 6 inputs (given as initial guesses) and the function returns value after solving it with the inputs.
Then, while trying to calculate Jacobians,
W=jacobian([f(1),f(2),f(3),f(4),f(5),f(6)],[theta,phi,omega,V,alpha1,beta1]);
Jacobian is evaluated and I get the partial derivatives accordingly.
But when I tried calling a function that calculates Jacobian W, with my initial guess. It does not give me a value, rather the partial derivative itself.
function X=jaccalc(input,W);
theta=input(1)
phi=input(2)
omega=input(3);
V=input(4);
alpha1=input(5);
beta1=input(6);
% other variables were also defined
for i=1:6
X(i)=W(i); %I tried assigning a matrix X in hopes that it would calculate the value with the inputs.
end
end
Kindly help me out. And any advice on making the code efficient is also much appreciated

That is your jacobian. Decimal would only be an approximation of the jacobian. But if you really want that then double() the answer you are getting .
