The following code is neither elegant nor memory efficient, but it appears to address your question:
function output = dec2octal(num)
output = '';
while num >= 8
fact = floor(num / 8);
num = mod(num,8);
output = [output num2str(fact)]; %#ok<AGROW>
end
output = [output num2str(num)];
end

It doesnt give the right answer, it should convert from decimal to octal using your code but the answer doesnt meet.

Algorithm:
if input is negative, error
if input is 0, emit '0' and return
initialize output to ''
assign input to a variable
while the variable is greater than 0 do
take mod8 of the variable
convert the mod8 to character, and put that at the beginning of the output
subtract the mod8 from the variable and divide by 8, and assign that result to the variable
end of loop
