Hello everyone, I have normalized a histogram for a vector contains around 19000 samples, after applying the normalization,I want to extract these data points and do some calculations that depends on the normalized data, my quistion is, is there any documintation about that ? I need to use these 19000 normalized samples not the original samples, Thanks.

在 MATLAB Online 中打开

See this doc (check for normalization under property of histogram): https://www.mathworks.com/help/matlab/ref/matlab.graphics.chart.primitive.histogram-properties.html?s_tid=srchtitle

Normalization of hist data can be done in a relatively simple way, e.g.:

    [H, xdata] = histogram(DATA,Bins);
    dx = abs(diff(xdata(1:2));
    Area = sum(dx*H);
    Hnor = H/Area;
    %%    

There are nice fcn files in MATLAB exchange:
