How to apply two masks simultaniously for plot

Hi all,

I have a data set of which I want to show the outcome in one plot. Four types of outcomes are possible: mask 1 & mask 2 are false, only one of those is true, and both are true. I can't figure out how the latter can be colored green. The last line of text is incorrect, but I can't find the right syntax.

Thank you all.

figure; hold on;  % new figure window. enable overlaying of plots
plot(x,y,'r.');   % plot a red dot for all points
plot(x(mask1),y(mask1),'m.') % overwrite all points where mask1==true
plot(x(mask2),y(mask2),'c.') % overwrite all points where mask2==true

plot(x([mask2]&&[mask1]), y([mask2]&&[mask1]), 'g.')%overwrite all point where mask1 & mask2 are true.

ixBoth=mask2&mask1;
plot(x(ixBoth), y(ixBoth, 'g.')

Not the place for && short-circuit operator, but the single & for logical addressing/indexing.

I dunno if ML JIT optimizer is smart enough to recognize and eliminate the double-calculation of writing both indexing expressions explicitly or not so I built the temporary here.

Thanks a lot, this works. I don't know why I didn't try this myself as it seems logical but I appreciate your answer!
