I have data stored in an array A from 1 to 400: A[1] =0, A[2]= 66.56, A[3]= 64.8, A[4]=56.8.....A[10] = 54.3, A[11]=73.3 ......... A[400] = 76.5
I wish to plot a bar graph in such a manner A[1] to A[10] in red color and A[11] to A[400] in blue color in a same graph. Can any one help me in this?

Try this —
A = rand(1,400);
x = 1:400;
figure
hb = bar(x, A);
hb.FaceColor = 'flat';
hb.CData(1:10,:) = [ones(10,1) zeros(10,2)];
xlim([0 50]) % Zoom To See Detail (Delete Later)
Experiment to get different results.

The legend was not part of the original request.
The only way to do that is to use the hold function and plot two separate bar objects. (I did some deep property spelunking and could not devise away to make the legend request compatible with my original code.)
A = rand(1,400);
x = 1:400;
figure
hold on
hb(1) = bar(x(1:10), A(1:10), 'r');
hb(2) = bar(x(11:end), A(11:end), 'b');
hold off
legend('Red Bars', 'Blue Bars', 'Location','bestoutside');
xlim([0 50]) % Zoom To See Detail (Delete Later)

N = 10;
bar(x(1:N), y(1:N), 'r');
hold on
bar(x(N+1:end), y(N+1:end), 'b');
hold off
