hist3(X) bins the elements of the m-by-2 matrix X into a 10-by-10 grid of equally spaced containers, and plots a histogram. Each column of X corresponds to one dimension in the bin grid.
hist3(X,nbins) plots a histogram using an nbins(1)-by-nbins(2) grid of bins. hist3(X,'Nbins',nbins) is equivalent to hist3(X,nbins).
hist3(X,ctrs), where ctrs is a two-element cell array of numeric vectors with monotonically non-decreasing values, uses a 2-D grid of bins centered on ctrs{1} in the first dimension and on ctrs{2} in the second. hist3 assigns rows of X falling outside the range of that grid to the bins along the outer edges of the grid, and ignores rows of X containing NaNs. hist3(X,'Ctrs',ctrs) is equivalent to hist3(X,ctrs).
hist3(X,'Edges',edges), where edges is a two-element cell array of numeric vectors with monotonically non-decreasing values, uses a 2-D grid of bins with edges at edges{1} in the first dimension and at edges{2} in the second. The (i, j)th bin includes the value X(k,:) if
edges{1}(i) <= X(k,1) < edges{1}(i+1) edges{2}(j) <= X(k,2) < edges{2}(j+1)
Rows of X that fall on the upper edges of the grid, edges{1}(end) or edges{2}(end), are counted in the (I,j)th or (i,J)th bins, where I and J are the lengths of edges{1} and edges{2}. hist3 does not count rows of X falling outside the range of the grid. Use -Inf and Inf in edges to include all non-NaN values.
N = hist3(X,...) returns a matrix containing the number of elements of X that fall in each bin of the grid, and does not plot the histogram.
[N,C] = hist3(X,...) returns the positions of the bin centers in a 1-by-2 cell array of numeric vectors, and does not plot the histogram. hist3(ax,X,...) plots onto an axes with handle ax instead of the current axes. See the axes reference page for more information about handles to plots.
hist3(...,param1,val1,param2,val2,...) allows you to specify graphics parameter name/value pairs to fine-tune the plot.
