V_CBLABEL add a label to a colorbar C=(L,H)
Usage: (1) imagesc(...)
colorbar;
v_cblabel('Colorbar label'); % label the closest colorbar to the current axis
(2) imagesc(...)
ch=colorbar;
v_cblabel('Colorbar label',ch); % label the explicitly specified colorbar
Inputs:
l Label string for colorbar
h Handle of the colorbar, axis or figure [default = current axis]
Outputs:
c Handle of the colorbar
