frequency of the values in a vector or matrix. This function is obsolete.

Calling Sequence




real or complex vector or matrix


Frequency of the values in a real or complex vector or a real or complex matrix x.

For a real or complex vector or a real or complex matrix x, m=freq(x) returns in the first column of the size(x,'*')x2 matrix m the values of x and in the second column of this matrix the frequencies of the corresponding values.

Note that the tabul function is more efficient, applies also to vector of strings and returns a sorted m.

This function is obsolete.
It is better to use tabul instead of nfreq.


x=[2 8 0 3 7 6 8 7 9 1]
