Listing values that fall into histogram

Hello! I've been trying to figure out how to see all values that fall into a certain bin size. Right now, my code looks like the following for two double arrays because my initial goal was to sum the bins (sum the biomass of each cell size, where the edges of the bin represent cell size (0.5-1, 1-2, 2-4, etc)

[dpb]

See histcounts -- the third optional argument returns bin of each observation.

[dpb]

Yet again, see the optional third output argument from histcounts

Answer 1

[dpb]

edges = 2.^(-2:14);
[N,~,bin]=histcounts(Cell_Biomass_001,edges);
BinSums=groupsummary(Cell_Biomass_001,bin,'sum');
