MATLAB 程式設計入門篇 : 初探 MATLAB輸出入變數的個數 (I)• 決定函數實際輸入輸出變數的個數• 使用內建變數 nargin 及 nargout• 主要功能• 設定未被指定之輸入引數的預設值• 避免計算未被用到的輸出引數 , 以節省計算時間110
MATLAB 程式設計入門篇 : 初探 MATLAB輸出入變數的個數 (II)• 上述函數 func3.m 可改寫成 func4.m>> type func4.mfunction [ave1, ave2] = func4(vector1, vector2)if nargin == 1,% 只有一個輸入變數ave1 = sum(vector1)/length(vector1);endif nargout == 2,% 有兩個輸出變數ave1 = sum(vector1)/length(vector1);ave2 = sum(vector2)/length(vector2);end111
