Function single to 4 bytes array

I want to create a function in MATLAB which converts a string into a 4 bytes array. I've found this function typecast which works perfectly, but I want to store the four bytes into my four outputs. 

tab = typecast(single(30),'uint8')

This gives tab = 00 00 f0 41. I try to display tab(0) but it shows the error

Subscript indices must be real positive or logicals

Can anyone help me to create the function and how to call it to get my four bytes? I want to include it in a Simulink block to do the conversion.

Solution

  • Indices in MATLAB start from 1, not 0. Try tab(1) instead.
