Why is my code only writing to the array 4 times?

word = input("Type a scrambled string: ", 's');

len = length(word)

totalPoss = factorial(len)
divisions = totalPoss/len
space = zeros(totalPoss,len);
%disp(space);

for i = 1:len
    for j = 1:divisions
        space((j + len*(i-1)),1) = word(i);
    end
end

disp(space);

When I run the above code in a Linux environment using octave, I expect to see the array space's firec column to be filled with the letters of the input, word.

For example, if the input were to be "lime," I would expect that space[1:6][1] to be "l," space[7:12][1] to be "i," etc. Instead, this is the output I am getting:

Type a scrambled string: lime
len =  4
totalPoss =  24
divisions =  6
   108     0     0     0
   108     0     0     0

     0     0     0     0
     0     0     0     0

I am unsure as to why the first three characters are only being inserted 4 times and why all of the extra spaces are at the bottom of the array. (I also don't know why the letters are ascii numbers, but that is a different problem I think).

You defined space as a double array:

space = zeros(totalPoss,len);

That is why it is printing as ASCII values. Try this instead:

space = repmat(' ',totalPoss,len);
