There is a function called hist(), but if I want to plot a graph without using hist() command, how to plot a graph? I means using command to do the job same as hist(). Thank you. Best Answer. 2015-09-26 It isn't a function to download by itself, it is just part of newer Matlab versions since R2014b so unless you upgrade to that version or later just ignore it. histogram includes various improvements over hist and is the new recommended function. This page gives some details of the changes between the functions.

There is a Matlab script to update former code to fit the way histogram is called (bin edges instead of bin centers - link ).

Matlab hist






MATLAB hist() A histogram is a plot presenting the distribution of values within a data set. To develop a histogram, the range of values within the data set is split into evenly spaced bins, and the number of data values falling into each bin is determined.

The values in the input array must be real. The orientation of vector outputs might not match the orientation in MATLAB ®.
