how to convert linear frequency to bode plot frequency

hello,

i want to know how i can convert linear frequency to decade log frequency scale as used in Bode plot. I don't want to use the matlab inbuilt functions as it would not help in real understanding.

thanks!!

I would do something like this if you want to emulate the logspace function:

linv = -1:3;                                % Linear Vector
logv = 10.^linv;                            % Homebuilt ‘logspace’ Function

logv =
          0.1            1           10          100         1000

I’m not certain what you want. Experiment with this idea to get the result you want.
