if ely == 10 & elx == 1, KE = 0; elseif ely == 11 & elx ==1,KE = 0; elseif ely == 12 & elx ==1,KE = 0; elseif ely == 13 & elx ==1,KE = 0; elseif ely == 14 & elx ==1,KE = 0; elseif ely == 15 & elx ==1,KE = 0; elseif ely == 16 & elx ==1,KE = 0; elseif ely == 17 & elx ==1,KE = 0; elseif ely == 18 & elx ==1,KE = 0; elseif ely == 19 & elx ==1,KE = 0; elseif ely == 20 & elx ==1,KE = 0; elseif ely == 11 & elx ==2,KE = 0; elseif ely == 12 & elx ==2,KE = 0; elseif ely == 13 & elx ==2,KE = 0; elseif ely == 14 & elx ==2,KE = 0; elseif ely == 15 & elx ==2,KE = 0; elseif ely == 16 & elx ==2,KE = 0; elseif ely == 17 & elx ==2,KE = 0; elseif ely == 18 & elx ==2,KE = 0; elseif ely == 19 & elx ==2,KE = 0; elseif ely == 20 & elx ==2,KE = 0; elseif ely == 11 & elx ==3,KE = 0; elseif ely == 12 & elx ==4,KE = 0; elseif ely == 13 & elx ==3,KE = 0; elseif ely == 14 & elx ==4,KE = 0; elseif ely == 15 & elx ==3,KE = 0; elseif ely == 16 & elx ==4,KE = 0; elseif ely == 17 & elx ==3,KE = 0; elseif ely == 18 & elx ==4,KE = 0; elseif ely == 19 & elx ==3,KE = 0; elseif ely == 20 & elx ==4,KE = 0; else KE = Q4K(v, E ); end 請問如何能將上述的判斷簡化至不用打那麼多行？！感謝解惑！！ ☆新年快樂☆ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.0.213.191
