"I need to switch the position and values of X and Y axes in plotting colormaps"
Do you mean instead of imagesc(x,y,c) you want imagesc(y,x,C)?
Or do you want to flip any of the axes using ax=gca; ax.YDir='reverse'or ax.XDir='reverse';?
Or do you want to change which side of the axes host the ticks and labels using ax.XAxisLocation='top'; ax.YAxisLocation='right'?
