colorspec_shortname_to_rgbvalue.m

在matlab中绘制3d箭头

function RGBvalue = ColorSpec_ShortName_to_RGBvalue(shortName)

% RGBvalue = ColorSpec_ShortName_to_RGBvalue(shortName) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%     
%     Given the single character shortName ('r','g',...) convert to the matrix equivalent
%         
% Example:
%     val = ColorSpec_ShortName_to_RGBvalue('m');
%     -------> returns the three-element equivalent to 'm' (magenta) = [1 0 1]
