MATLAB 程式設計入門篇 : 初探 MATLAB資料儲存的注意事項• 整數資料型態的範圍有限 , 若超過此範圍 , 則超出部分將會被「裁掉」>> uint8(300) % uint8 的最大值為 255ans =255>> int8(-500) % int8 的最小值為 -128ans =-128• 整數資料型態可以比較大小 , 但不可直接進行數學運算>> uint8(20)== 20 % 可比較大小ans =1>> uint8(20)-20 % 無法進行數學運算??? Error using ==> -Function '-' not defined for variables of class 'uint8'.• 若要進行數學運算 , 需先用 double 指令將之轉成雙精準浮點數才能進行88
