I am trying to plot data (45*56*6) only inside polygon and i tried these steps
imported shapefile and run query to sperate data point inside and outside polygon as
for i=1:6;
isin = inpolygon(X,Y,S.X,S.Y);
test(:,:,i(~isin)) = NaN;
end;
and plot
for i =1:6
subplot(3,2,i);
imagesc(D_masked(:,:,i));
set(a,'AlphaData',~isnan(a))
end
but it did not work for me as
imagesc(xyz,'AlphaData',~isnan(xyz))
xyz here is equal to 45*56 2d data.
Any kind of help is appreciatable.

It can be done...what problem you are facing? Don't use imagesc. Use pcolor.

In first section crossponding values of each slice of 3d data with logical 2d data has to replace with NaN by keeping rest of all values as it is (that are 0-100) which I could not figure out. Secondly I would like to use imagesc instead of pcolor.
