For loop and subplot

I have a for loop and in each loop I plot to figures. I want each pair of figure to be plotted next to each other (left and right).

I mean for i=1 I have two plots. I want one to be on the left and one on the right and so on.

I tried subplot(6,2,i); and subplot(6,2,i+1); in each loop but did not work. i=1 would plot on the first row left. i=2 would plot on the 1st row right but I wanted to plot on the second row left.

subplot(6,2,2*i-1)
subplot(6,2,2*i)

Thanks. But I wanted to find a systematic way. I mean is there any structure that I can define in matlab so it can place the plot where I want?

[Walter Roberson]

plots_down = 6; plots_across = 2;
subplot( plots_down, plots_across, sub2ind([plots_across, plots_down], column_of_plot, row_of_plot))

For example,

%notice the 6, 2 in one place but the 2, 6 in the other case
subplot(6, 2, sub2ind([2, 6], 1, i))     %left
subplot(6, 2, sub2ind([2, 6], 2, i))     %right

This can be done more directly by using the formula for sub2ind directly, as

subplot( plots_down, plots_across, (row_of_plot-1)*plots_across + column_of_plot)

which for 2 plots across would be

subplot( plots_down, 2, (i-1) * 2 + 1)  %left
subplot( plots_down, 2, (i-1) * 2 + 2)  %right

and in your particular case that would optimize as

subplot(6, 2, 2*i - 1)    %left
subplot(6, 2, 2*i)         %right

so this is a systematic way.

Use this simple scheme i created for you

Numbers in mesh indicates number of subplot

subplot(3,2,i)
