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 matrixx, m=freq(x) returns in the first column of the size(x,'*')x2 matrix m the values ofx 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)
