How can I move a colorbar when using heat maps? (2017a) I keep getting the error:

Error using matlab.graphics.chart.Chart/colorbar Output arguments are not supported when using colorbar with heatmap.

Using 2017a

subplot('Position',[0.16 0.065 0.762 0.11])
heatmap(p_index, s_num, inc_diff(s_num,:), 'ColorLimits', [real_min, real_max], 'GridVisible', 'off', 'CellLabelColor', 'none');
xlabel('Parameter')
set(colorbar,'Position',[0.9 0.1 0.07 0.8])

在 MATLAB Online 中打开

That does not appear to be possible.

heatmap() turns out to create a sort of axis object, and colorbar notices that its parent is a heatmap and refuses to do some things.

If you do

ax = gca;     %then ax becomes the handle to the heatmap
axs = struct(ax);   %and ignore the warning
cb = axs.Colorbar;    %now you have a handle to the colorbar object

However, if you try to set cb.Position then that will fail: the colorbar is being controlled by a layout manager which will promptly get confused and error out.
