Hello,
Is there a way to extract histogram data into a matrix instead of a graph?
for mer= start:Add:N_Mer
FileName_1 = ['Info_',num2str(N_Mer),'.mat'];
disp([FileName_1,' Running'])
M=load(FileName_1);
all_rows=cell2mat(struct2cell(M));
R_sqr{N_Mer}=all_rows(1,:);
FileName=(['hist_R2',num2str(N_Mer)]);
hist_R2{N_Mer}=histogram(R_sqr{N_Mer});
legend
hold on
end

If you want to make a plot and also extract the values
% some data
foo = randn(10000,1);
% make a histogram named h
h = histogram(foo);
% get the values of the histogram
binedges = h.BinEdges;
binwidth = h.BinWidth;
bincounts = h.Values;
Alternatively, if you don't want a plot, but just want to extract histogram information
% some data
foo = randn(10000,1);
% extract histogram data
[bincounts, binedges] = histcounts(foo);

The bin counts are fence rails/sections, the bin edges are the fence posts. See the Wikipedia page for "off by one error".
Ten bins would require eleven bin edges as shown in the picture in the "Fencepost error" section on that Wikipedia page.
