在matlab中绘制3d箭头

function RGBvalue = ColorSpec_LongName_to_RGBvalue(LongName)

% RGBvalue = ColorSpec_LongName_to_RGBvalue(LongName) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%     
%     Given the color 'LongName' ('red','green',...) convert to the matrix equivalent
%         
% Example:
%     val = ColorSpec_LongName_to_RGBvalue('magenta');
%     ------> returns the three-element equivalent to magenta = [1 0 1]
