i am trying to find the entropy of an audio signal, so i need first the probability of appearance of each values of the signal, the problem is, i have this values due to the histogram i did but how can i get those values and save them into a vector in order to fins the entropy? i already have the entropy function!

If f is a scalar, x is interpreted as a time-domain signal, and f is interpreted as the sample rate. In this case, x must be a real vector or matrix. If x is specified as a matrix, the columns are interpreted as individual channels. If f is a vector, x is interpreted as a frequency-domain signal, and f is interpreted as the frequencies, in Hz, corresponding to the rows of x.
