function c = summer(m)
%SUMMER Shades of green and yellow colormap
%   SUMMER(M) returns an M-by-3 matrix containing a "summer" colormap.
%   SUMMER, by itself, is the same length as the current figure's
%   colormap. If no figure exists, MATLAB creates one.
%
%   For example, to reset the colormap of the current figure:
%
%       colormap(summer)

%   See also HSV, GRAY, HOT, BONE, COPPER, PINK, FLAG, 
%   COLORMAP, RGBPLOT.
