quick way to singles array to byte array

[George Nychis]

Hi all,

Let's say I have an array of singles, like:
a=[0.923834,0.8234234,0.234234,0.23414]

If I want to convert this to a byte array, where each number is represented by 4 bytes, I've been doing:
b=[];
for i=1:length(a)/2
  b=[b;typecast(single(a((i-1)*2+1)),'uint8');typecast(single(a((i-1)*2+2)),'uint8')]
end

Is there an easier, less complex way of doing this?

Thanks!
George
