How can I remove some specific lines from this contour plot

I'm a learner in the matlab. This streamline plot is for lid driven cavity with top wall in motion.

I used in this plot around 100 contour lines but I don't want so many contour lines in the plot and if I take less contour lines using

contour(streamline,20)

'then the plot doesn't provide information about small eddies at the corners.

So my Question is that how can I remove specific lines from a contour plot for a higher number of contour lines.

You can specify the levels in contour. Read the documentation.

Easy way is that you can select "Edit" option from the figure window after plotting and click on figure properties. Then click on the lines you wish to delete using mouse. Once you click on the figure it will allow you to select the specific lines to be delete.

Hope it helps
