'rows' : frequency of each row
'1x' : single bin-values
'nx' : separate bin-values for each column
X are the bin-values H is the frequency of occurence of value X
HISTO(Y) with no output arguments: plots the histogram bar(X,H) more histogram-based results can be obtained by HIST2RES2 see also: <a href="histo.html" class="code" title="function [H,X]=histo(Y,Mode)">HISTO</a>, <a href="histo2.html" class="code" title="function R=histo2(Y)">HISTO2</a>, <a href="histo3.html" class="code" title="function [R,tix]=histo3(Y)">HISTO3</a>, <a href="histo4.html" class="code" title="function [R,tix]=histo4(Y)">HISTO4</a> REFERENCE(S): C.E.
