Contourf matrix plot contour

I have written a code to graph contours of a matrix in 2D. However, although i have values of MY2 <10, when it is plotted there is a white area for MY2<10. Would you please help me with this. I have checked this several times and it seems to be alright!

Please show the contourf() call you use.

Answer 1

[Walter Roberson]

The call

[C,M]=contourf(MX2,MY2,MR2,10);

requests that 10 contour levels be used, not a single contour level at value 10. To use a single contour level at value 10, code

[C, M] = contourf(MX2, MY2, MR2, [10 10]);

Thanks i will try your suggestion now. But I meant to have the contour values of MR2, MV2 and MU2 when MY2=10 or less. Currently the region with MY2<10 has no contour of MR2, MV2 or MU2 and is solid white.

Any help is highly appreciated

Why not use logical indexing to find the cut-plane for MY2 being 10, and applying that logical index to MX2, MY2, MR2, and contourf() the result ?
