hist
calculates or plots histograms.
hist(y)
draws a 10-bin histogram for the data in vector y
. The bins are equally spaced between the minimum and maximum values in y
.
hist(y,nb)
draws a histogram with nb
bins.
hist(y,x)
, if x
is a vector, draws a histogram using the bins specified in x
.
[n,x] = hist(y)
, [n,x] = hist(y,nb)
, and [n,x] = hist(y,x)
do not draw graphs, but return vectors n
and x
containing the frequency counts and the bin locations such that bar(x,n)
plots the histogram. This is useful in situations where more control is needed over the appearance of a graph, for example, to combine a histogram into a more elaborate plot.
x = -2.9:0.1:2.9;
y = randn(10000,1);
hist(y,x)
