Didnt clearly understood about "delete untitled.htlm'.
Its mean every times ones run this he had to delete this previously created resulting plot?

@VolKa79 no that was the commit mistake-
I had that file additional in the folder, which i did not notice during PR.

it has nothing to do with the issue code

this commit perform two modifications in the last merged issue code-

1. ischar(temp_plots.FaceAlpha) can throw an error if FaceAlpha property is not present, so I have updated it to isprop() which will not throw any error in case if the property is not present.

2. second addition, specify the case, only which was originally intended to solve, so that by any chance no other case falls under this scenerio, other than the expected (see issue 207, plotmatrix(X))

@xarico10 please review it sooner!
