using 3 arrays R,S and T I want to make a scatterplot,but it takes a lot of time to save the scatterplot and sometimes crashed. How can I improve it?
bb= find(R>=0.2 & R <0.4);
x2 = S(bb);
y2 = T(bb);
figure(2)
scatter(x2,y2,'MarkerFaceColor','b','MarkerEdgeColor','b');
saveas(gcf,'420bbh.tiff', 'tiffn') saveas(gcf,'420bbh.fig')

I think you need to consider another kind of plot. Your monitor doesn't even have that many pixels!

Then remove them before scattering!
Otherwise, they still need to be transmitted.

Here's one way to remove:
idxNan = isnan(x)|isnan(y);
x(idxNan) = [];
y(idxNan) = [];
