Hello!
I am very new to MatLab. I am wondering, what is the simplest way to convert a 5-digit number into a matrix of those 5 digits.
Thanks,

fix(rem(TheNumber*10.^-(ceil(log10(TheNumber)):-1:1),1)*10)

sprintf('%d', TheNumber) - '0'
is the simplest, but not the most efficient.

You can do that by simply using the following code:
p = 12345; % define your number
pstr=num2str(p);
n=length(pstr);
v=zeros(n,1);
for k=1:n
v(k)=str2double(pstr(k));
end
It will work for all integer numbers. For non Integer numbers, the "." will be transformed into 'NaN'.

When you are dealing with single digits, subtracting the character '0' is much more efficient than str2double().
