Discrete histogram
distfun_inthisto(data) distfun_inthisto(data,nrmlz) H = distfun_inthisto(...)
a n-by-1 or 1-by-n matrix of doubles, integer value, the discrete data.
a 1-by-1 matrix of booleans, true to normalize the histogram, false to plot the unnormalized histogram (default nrmlz=%t)
a n-by-2 matrix of doubles. H(:,1) is the X coordinate of the histogram and contains the unique data entries. H(:,2) is the Y coordinate of the histogram. If nrmlz is false, H(:,2) is the number of occurences of the corresponding value in H(:,1). If nrmlz is true, H(:,2) is the fraction of the data equal to the corresponding value in H(:,1).
Plots the empirical histogram of a set of discrete values.
The data is not normalized, then the entries in H(:,2) have integer values in the range {0,1,2,...,n} and sum(H(:,2))==n. In this case, H(i,2) is the number of times H(i,1)==data, where i=1,2,...,n.
The data is normalized, then the entries in H(:,2) are real values in the range [0,1] and sum(H(:,2))==1. In this case, H(i,2) is the number of times H(i,1)==data divided by n, where i=1,2,...,n.
The difference with the histplot function is that histplot is well suited for real values, while distfun_inthisto well suited for integer values. More preciselly, the classes in distfun_inthisto are the unique entries in the data, while histplot considers intervals.
