I am not getting a graph when I use mesh

Dear sir/madam,

When I use mesh() or surf() to plot the graph, I am not getting any graph. It displays only the co-ordinate axes, and nothing in it. It will be totally blank. I am unable to find out the reason for this. Looking forward to hearing from you soon.

Thanking you, BSD

If you were somehow accidentally submitting only a single point to mesh() or surf() then your graph might look blank.

Have you tried tests such as surf(rand(50,50))

Or if the matrix is all(nan)
