How measure a 0.5 delta of a vector?

Hi everyone,

Truly appreciated to direct me in advance!

I have a vector (a signal) and I need to measure the half d of natural logarithm of the signal. How should write the code? Thank you!

RC=0.5 d ln A.

Come on.....it is a simple one. Read some basics of MATLAB.

x = rand(10,1) ; 
iwant = 1/2*log(x)

iwant = 10×1

-0.6282 -0.1741 -0.0227 -0.4696 -0.3884 -1.1212 -1.7144 -0.0485 -0.5902 -0.4798

Dear KSSV, I was thinking about "d" in the equation. is" 0.5 d" equal "0.5" in MATLAB? Thank you!

[KSSV]

If d stands for double, the default number in MATLAB is double unless you fix it.

KSSV, thanks but here d stands for delta in the reference book and I guess it means dirac delta,

Then, is your answer working for that?

[KSSV]

Then answer is not what you want.

KSSV, Thank you for all your explanation!
