I'm not sure what that means. The origin is always at (0,0). Do you want the axes to be at some particular location, like in the middle of plot instead of outside at the lower left?

i want the axes to be at point other than bottom , left or top right or at origin. i want to plot the axes at say xaxis=107 nad yaxis=98 so the axes centre or intersection points will be at (98,107)

Here is an example
plot(0:9,0:9);
set(gca,'XTickLabel',get(gca,'XTick')+98);
set(gca,'YTickLabel',get(gca,'YTick')+107);

Maybe you want something like this:
% Setup - generate some random sample data.
numPoints = 50;
x = linspace(95, 105, numPoints);
y = 107 + 8 * rand(1, numPoints);
% Plot the data.
plot(x, y, 'b-');
grid on;
% Add axes going through (98,108)
xl = xlim;
yl = ylim;
hold on;
line([98, 98], yl, 'Color', 'k', 'LineWidth', 3);
line(xl, [108, 108], 'Color', 'k', 'LineWidth', 3);
If not, then upload a picture of what you want.
