function [whatsLeft, divisionCount] = divideBySeven(number) %Enter the code for your function here. while number < 1 number = number / 7 divisionCount = divisionCount + 1 end whatsLeft = number this is my code to call my function: [whatsLeft, divisionCount] = divideBySeven(256) I tried to run this and the error was that: Output argument "divisionCount" (and maybe others) not assigned during call to "divideBySeven".

在 MATLAB Online 中打开

function [whatsLeft, divisionCount] = divideBySeven (number)
% Enter the code for your function here.   
while number <1
    number = number / 7
    divisionCount = divisionCount + 1    
end    
whatsLeft = number

In the above you are using the variable divisonCountinside the loop and you have not defined it. You have to define it.

function [whatsLeft, divisionCount] = divideBySeven (number)
% Enter the code for your function here.   
divisionCount = 0;
while number <1
    number = number / 7
    divisionCount = divisionCount + 1    
end    
whatsLeft = number
