Hello,
When I am using this command for to see the prob of occurrence
P = histc(B(:,i),0:255)/length(B(:,i));
Where i varies from 1 to 65 and each B contains 2560 character (ASCII)so ranging from 0 to 255
but when I am using
[(0:255).' P(:)]
I am about see prob of occurrence of each 0 to 255 ASCII characters but it's showing in this way
0 0.000035156250000
0.010000000000000 0.000042968750000
0.020000000000000 0.000042968750000
0.030000000000000 0.000027343750000
0.040000000000000 0.000058593750000
0.050000000000000 0.000058593750000
0.060000000000000 0.000039062500000
.................
2.540000000000000 0.000066406250000
2.550000000000000 0.000042968750000
Why 2.55 not 255?

Show the line of code where you actually use this: [(0:255).' P(:)], because you can't have that as an output of histc() because your first output argument is a constant, not a variable. And P has a different meaning when it's the second output argument than when it's the first.

Give the command
format long g
before showing the output.
