I have both matrix...just wanna do a scatter plot with them...plot (SO, PO, 'o') but the last 3 rows does not appear in the graph.
S0 = [0.50 0.40 1.10 0.20 0.50 3.40;...
0.30 0.30 0.50 0.80 1.20 9.20;...

Try this:
fontSize = 15;
SO = [0.30 0.30 0.50 0.80 1.20 9.20;...
0.20 0.10 0.20 1.10 2.40 2.50;...
0.20 0.00 0.60 2.70 7.20 16.00;...
0.10 1.10 1.90 1.10 1.50 0.40;...
1.30 1.40 2.70 3.80 7.10 6.30;...
3.00 2.70 2.60 2.80 1.80 1.80;...
1.8 1.4 0.70 0.30 0.90 0.7;...
0.70 15.10 14.70 6.10 3.10 2.20];
PO = [104.3 79.4 20.5 18.6 76.2 284.9;...

41.4 156.3 171.2 206.4 84.0 38.8;...
92.2 30.7 66.4 37.1 38.4 100.9;...
10.4 17.0 50.1 36.6 43.8 38.9;...
4.1 270.2 156.1 17.7 10.1 19.8];
sz = min(size(SO), size(PO))
% Get colors for each row
cmap = jet(sz(1));
for row = 1 : sz(1) % For as many rows as the one with the fewest rows has...
% Get the data from this row only.
thisSO = SO(row, :);
thisPO = PO(row, :);
% Get a unique color for the spots of this row.
thisColor = cmap(row, :);
% Make a scatterplot of the points in this row only.
scatter(thisSO, thisPO, 50, thisColor, 'filled');
hold on;
legendStrings{row} = sprintf('Row %d', row);
end
xlabel('SO', 'FontSize', fontSize);
ylabel('PO', 'FontSize', fontSize);

legend(legendStrings);

OK, but my code will still work as is. You just have to change the one variable name from SO to S0 because you changed the name. Here is the new code:
fontSize = 15;
S0 = [0.50 0.40 1.10 0.20 0.50 3.40;...
0.30 0.30 0.50 0.80 1.20 9.20;...
0.20 0.10 0.20 1.10 2.40 2.50;...
0.20 0.00 0.60 2.70 7.20 16.00;...
0.10 1.10 1.90 1.10 1.50 0.40;...
1.30 1.40 2.70 3.80 7.10 6.30;...
3.00 2.70 2.60 2.80 1.80 1.80;...
1.8 1.4 0.70 0.30 0.90 0.7;...
0.70 15.10 14.70 6.10 3.10 2.20];
PO = [104.3 79.4 20.5 18.6 76.2 284.9;...
56.1 71.5 31.5 28.3 26.2 217.9;...
253.5 151.8 41.3 35.8 47.3 39.5;...
27.9 25.3 20.6 18.7 60.5 259.2;...
19.0 39.0 206. 198.7 123.7 50.3;...
41.4 156.3 171.2 206.4 84.0 38.8;...
92.2 30.7 66.4 37.1 38.4 100.9;...
10.4 17.0 50.1 36.6 43.8 38.9;...
4.1 270.2 156.1 17.7 10.1 19.8];
fontSize = 15;
sz = min(size(S0), size(PO))
% Get colors for each row
cmap = jet(sz(1));
for row = 1 : sz(1) % For as many rows as the one with the fewest rows has...
% Get the data from this row only.
thisSO = S0(row, :);
thisPO = PO(row, :);
% Get a unique color for the spots of this row.
thisColor = cmap(row, :);
% Make a scatterplot of the points in this row only.
scatter(thisSO, thisPO, 50, thisColor, 'filled');
hold on;
legendStrings{row} = sprintf('Row %d', row);
end
xlabel('SO', 'FontSize', fontSize);
ylabel('PO', 'FontSize', fontSize);
grid on;
legend(legendStrings);
Is there some reason this is not what you're looking for? Like maybe you want no legend, or a different colormap or something? If so, please say what you want.

SO only has 8 rows. And Ofcourse supply matrices as a vector using (:)
