I want to make a filled Ellipsoid
, but it seems Filling
options doesn't work in Graphics
options. I have a matrix
matrix1={{1,4},{6,8}}
thus I plot en ellipse from his Eigenvalues
and Eigenvectors
valmat = Eigenvalues@matrix1;
vecmat = Eigenvectors@matrix1;
pair = {0.5, 0.5}
ellips1 =
Ellipsoid[pair, {Abs[valmat[[1]]], Abs[valmat[[2]]]}, {vecmat[[1]], vecmat[[2]]}];
plot1 = Graphics[{Red, ellips1}, GridLines -> Automatic,
GridLinesStyle -> Directive[Gray, Dotted]];
partot1 =
Show[plot1, Frame -> True,
FrameLabel -> {Style["x", 18], Style["y", 18]}, AspectRatio -> 1,
FrameTicks -> {Automatic, Automatic, None, None},
LabelStyle -> Directive[13], ImageSize -> 500]
The question is how to filled this ellipse with an specific color??..and also (if it's possible) the transparency on that. Thanks
Ellipsoid
