Matlab help, I don't know which part is wrong.

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.

Instead of your function, just use the built-in function dec2bin

binaryNumber = dec2bin(decimalNumber)
