如何在条件中使用用户输入 (MATLAB)

Question

我制作了一个带有用户输入的简单球体计算器：

clc

%Ask For Radius
radius = input ('What is the radius of your sphere?');

%Calculate Volume Using Radius
vlm = (4/3) * pi * radius^3 ;

%Return Radius
fprintf('The volume of your sphere is %4.2f inches cubed\n', vlm)

但我决定更进一步，让用户可以选择问一个又一个，直到他们不想再问了。但是我被卡住了，因为我不知道如何接受这个用户输入：

again = input ('Do You Want To Find The Volume Of A Sphere?','s')

并将其应用于条件语句，例如 if else 语句。以下是我到目前为止的想法：

if again = yes
    %Ask For Radius
    %Insert VolumeOfSphere.m
else 
    fprintf('Ok, Just run Me Again If You Want To Calculate Another Sphere')
    %Add An End program Command
end

非常感谢任何正确方向的帮助或提示。

excaza 是对的，while 循环听起来正是您所需要的。一个基本的实现可能是：

clc; clear;

while true
    %Ask For Radius
    radius = input ('What is the radius of your sphere?  ');

    %Calculate Volume Using Radius
    vlm = (4/3) * pi * radius^3 ;

    %Return Radius
    fprintf('The volume of your sphere is %4.2f inches cubed\n', vlm)

    % Ask if they want to run again
    run_again = input('\nWould you like to run again? Y or N:  ', 's');

    % Deal with their answer
    if     strcmpi(run_again, 'Y')
        % do nothing, let the loop keep running
    elseif strcmpi(run_again, 'N')
        break % this will break out of the while loop and end the program
    else
        % assume they meant Y, and send them back to the start
    end

end
