How to set x axis values in MATLAB

I'm working with some signal. The signal has some length (time) and I devided it into 200 pieces and made some operations over them. The results are saved in matrix, so the matrix has one of the dimensions 200 and if I use imagesc() on it, to make results visualy readable, the x axis is from 0 to 200. But that does not correspond to time. The time is function of the values in x axis.

t = 640 * x

I need to make values in x axis to correspond to time. Is there any way, how to do this?

Use set and set the XTick and the XTickLabel properties accordingly. Assuming your image is already open, do this:

set(gca, 'XTick', 0:20:200);
set(gca, 'XTickLabel', 640*(0:20:200));

I used increments of 20 so that you don't clutter the x-axis. Modify the 20 to suit your tastes.
