Hi, I have to plot the following function on a 3d graph, it should be an ellipsoid. theta_ is a 1x3 vector and COV a 3x3 matrix
RC=@(x,y,z) (theta_-[x y z])*inv(COV)*(theta_-[x y z])'-5;

theta_ = [1 2 3];
COV = cov(rand(10,3)); % picking some arbitrary values for theta_ and COV...
RC=@(x,y,z) (theta_-[x y z])*inv(COV)*(theta_-[x y z])'-5;
fimplicit3(RC)
Warning: Function behaves unexpectedly on array inputs. To improve performance, properly vectorize your function to return an output with the same size and shape as the input arguments.
