histogram normalized in matlab

To create a normalized histogram in Matlab, you can use the histogram function with the 'Normalization' parameter set to 'probability'.

Here's an example:

main.m
% Generate some sample data
data = randn(1000, 1);

% Create a normalized histogram with 20 bins
histogram(data, 20, 'Normalization', 'probability')
149 chars
6 lines

This will create a histogram with 20 bins, where the y-axis represents the probability density. Note that the sum of the areas of all bars will be equal to 1, which represents the total probability of the data set.
