im trying huffman encoding in matlab and reached the part where i get a table with huffman codes, what's next ?

Hello, so i have being trying to implement huffman encoding for an image compression project i got, and in my code im able to reach where i get a table of each symbol and it's code such as the one im posting below, but im not quite sure what i do after this, should i replace each pixel in my image with the new code as a string, or should i combine multiple codes and store each 8 bits on it own, or what ? since you cant save a value as binary in matlab im not quite sure where to go from this

Symbol  Probablity      Code
