function J = jet0(m)
%JET0    Variant of JET.
%   JET0(M), a variant of JET(M), is the colormap used with the
%   NCSA fluid jet image, but with the central colors set to white.
%   JET0, by itself, is the same length as the current colormap.
%   Use COLORMAP(JET0).

%   See also JET, HSV, HOT, PINK, FLAG, COLORMAP, RGBPLOT.
