Error using colormap (line 58)
First argument must be a scalar axes or figure handle.
I know cmap is holding the position of the item in the list. I want the value so that i can use in in colormap
Thanks

cmap=menu('Choose color','jet','hsv','summer','cool','spring','hot','autumn',...
'winter','bone','copper','pink','lines','Gray'); % menu returns index of selected choice.
map={'jet','hsv','summer','cool','spring','hot','autumn',...
'winter','bone','copper','pink','lines','Gray'};
colormap(map{cmap});
