Trying to write a function to convert a decimal number to a binary number.

function [binary] = myDecimal(decimal)
    binary = [];
    while decimal > 0 
        binary = [mod(decimal,2) binary]; 
        decimal = floor(decimal/2); 
    end
end
%codes to call the function
% Run learner solution.
decimal = 7;
binary = myDecimal(decimal); 
% Run reference solution.
binaryReference = reference.myDecimal(decimal); 
% Compare.
assessVariableEqual('binary', binaryReference);

@Ryan W - which part of your code do you think is incorrect? I don't understand the line

% Run reference solution.
binaryReference = reference.myDecimal(decimal); 

which I assume you have so that you can compare a known binary string with the result from your algorithm. Consider using dec2bin which will create a string (so that will mean that you need to change your algorithm to create a string too).

What leads you to believe your solution is incorrect?

Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support so we can investigate.
