I want to plot contour plots of temperature which is the output of my program. It is a 2D plot so. I am plotting with the following command [cout hand] = contour(theta). In the program I get values of theta(i,j) for i in the range of 2 to 17 and j from 2 to 29. However the plot of theta shows it from i and j starting from zero. How should I plot such that I get it from point (2,2).
