nfreq
frequence of the values in a vector or matrix
Calling Sequence
m=nfreq(x)
Arguments
- x
real or complex vector or matrix
Description
Frequence 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
frequences of the corresponding values.
Note that the tabul function is more efficient, applies
also to vector of strings and returns a sorted m.
Examples
x=[2 8 0 3 7 6 8 7 9 1] m=nfreq(x)
