Code to split data taken from user in 32 bits block

I am working on a project to encipher data in Matlab using the blowfish algorithm. That is why I need a code to split data taken from the user into blocks of 32 bits. Also I don't want to use a file to read the data because I read that it might be time consuming in case of matlab , but any suggestions are welcome in that case too.

Here is a link to the code that I have worked on - link I found out that each character's length is 2 bytes.Using that , I was working on a code like this but I think this is wrong.

note: I want a code that gives me block of 32 bits in string

word = cell(1,10000);

 for i=1:2:length(str)-2
    word{1,i} = str(i:i+1);
 end

typecast() your data to uint32. dec2bin(). cellstr()
