建议的直方图函数中的Bin中心-Matlab

Question

Matlab now recommends to use the histogram in place of hist, however doesn't display an obvious way of finding the bin centers like the previous function.

My current code that works fine with the hist function:

figure

[counts171,position171] = hist(image171_reshaped,200);

plot(position171,log(counts171));

How would I be able to transform this piece of code in order to incorporate a recommended function such as 'histogram' or 'histcounts' in place of 'hist', while still obtaining the bin centers?

Answer 1

histcounts returns edges instead of bin centers and bin centers are midpoints between consecutive elements of the edges. So using diff function bin centers can be obtained:

[counts171,edges171] = histcounts(image171_reshaped,200);

position171 = edges171(1:end-1) + diff(edges171) / 2;
