Number to matrix

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,

What do want as the output, numbers (integers, doubles, etc.) or characters?

I want to convert it to integers.

As in, 12345 into [ 1 , 2 , 3 , 4 , 5 ]

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'.

Maybe some more details:

I convert the number to a string with num2str, then I take each character of the string and transfort it back to a number.

If you want to have a row vector instead of a column, just replace

v=zeros(n,1); by v=zeros(1,n);

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