I follow the example of the documentation here and I get stuck because I have an array called ``simdata`` which is 100 x 3200. I want to plot a contourf using the example I included here. How can I do this with a 2D array?

Z = peaks(100);

zmin = floor(min(Z(:)));

zmax = ceil(max(Z(:)));

zinc = (zmax - zmin) / 40;

zlevs = zmin:zinc:zmax;

% Plot the contour lines.

figure

contour(Z,zlevs)

zindex = zmin:2:zmax;

% Retain the previous contour plot. Create a second contour plot and use zindex to highlight contour lines at every other integer value. Set the line width to 2.

hold on

contour(Z,zindex,'LineWidth',2)

hold off
