How should i write if i need to calculate MSE using the values from the first row in my original variable called ori_bytes and the first row of my compressed variable call comp_bytes? Then the system need to continue calculating MSE until the last row. I have 100 rows in both ori_bytes and comp_bytes

all_mse = sum((double(ori_bytes) - double(comp_bytes)).^2, 2);
No loop needed.
This assumes that your "comp_bytes" are what has been reconstructed by compression and decompression.

how can I change the value of my data from double to floating? is that even possible? I get my MSE ^11 which is very big. I believe MSE should be ^-ve number right?
