Hello there, I need help with an simple Octave Code,
which shows me this error: >> a=numgrad(y,2) error: 'x' undefined near line 27 column 5 error: called from y at line 27 column 4 for the following function: function a = numgrad (fname,x) h=10^(-8); n=length(x); for i=1:n a(i)=(feval(fname,x+h*einheitsvektor(n,i))-feval(fname,x-h*einheitsvektor(n,i)))/(2*h);
end Thank you! |
