Superimpose a curve on a a image generated by 'imagesc' command, I need to keep two different Y-axis.

First, I have generated a image plot using the the command 'imagesc' with a data matrix 'A'. I have fixed the Y-axis limits (as it is needed).

Now I have to plot a curve (t) on the same image plot with same X-axis but different Y-axis scale.

Requirement is, the Y-axis corresponding to the image plot should be on left side and the Y-axis corresponding to the curve should be on right side.

>>imagesc(x,y,A); hold on; plot (x,t);

Please give suggestions how to handle axis in this case ?

Thank you ......
