nan_histo

calculates histogram for each column

Calling Sequence

[H,X] = nan_histo(Y,Mode)

Parameters

input:

Mode :

'rows' :

frequency of each row

'1x' :

single bin-values (default Mode)

'nx' :

separate bin-values for each column

'plot':

if one input parameter is 'plot', the histogramm bar(X,H) will be plotted

output:

X :

are the bin-values

H :

is the frequency of occurence of value X

Description

more histogram-based results can be obtained by hist2res
