Matlab，有關循環的基礎知識

Question

我需要詢問用戶溫度，k或K代表開爾文，c或C代表攝氏溫度，f或F代表華氏溫度。我怎樣才能把所有這些放在一個循環中？我需要不斷詢問用戶，直到他們輸入上面的一個字母。這是我迄今爲止所擁有的。

tempType = input('What type of temperature would you like to use: ', 's'); 

    value = ['k','K','c','C','f','F']; 

    while strcmp(tempType, value) == 1 

    tempType = input('What type of temperature would you like to use: ', 's'); 

    end 

Answer 1

你想(length(tempType)~=1 || length(findstr(tempType,value))==0)成爲你而

Answer 2

我寧願做這樣以避免出現兩個完全相同的行（在R2011b測試）的條件：

AllowedTemperature = {'k','K','c','C','f','F'}; 
SelectedTemperature = ''; 
while ~any(strcmp(SelectedTemperature,AllowedTemperature)) 
    SelectedTemperature = input('What type of temperature would you like to use: ', 's'); 
end 
disp([ 'SelectedTemperature: ' SelectedTemperature ])
