I am trying to draw ellipse using following code:

ell_x_end=[86.9279,144.30717,190.12074,217.43901,221.78224,219.34441]';

ell_y_end=[385.2701,385.78540,388.83215,393.49023,394.26529,393.99121]';

ellipse_dim_end=fit_ellipse(ell_y_end,ell_x_end,1);

theta_end=rad2deg(ellipse_dim_end.phi);

But getting a warning:

'Warning: fit_ellipse: Did not locate an ellipse '

Also sometimes it is showing an error: dot indexing is not supported.

fit_ellipse??

There is no Matlab inbuilt function fit_ellipse, hence, it is quite unclear what you are doing. However, a couple of days ago we discussed some properties of ellipses including drawing them at

https://www.mathworks.com/matlabcentral/answers/497966-how-to-find-the-vertical-height-of-an-ellipse-y-axis-length-of-ellipse

You can look and try this.

I am having few x and y coordinates and want to draw ellipse and find the orientation angle

I see. You should better address the author of fit_ellipse directly and discuss. Besides helping you, this can help the author to improve that program.
