Syntax
n = histc(x,edges) n = histc(x,edges,dim) [n,bin] = histc(...)
Description
n = histc(x,edges)
counts the number of values in vector x that fall between the elements in the edges vector (which must contain monotonically non-decreasing values). n is a length(edges) vector containing these counts.
n(k) counts the value x(i) if edges(k) > x(i) >= edges(k+1). The last bin counts any values of x that match edges(end). Values outside the values in edges are not counted. Use -inf and inf in edges to include all non-NaN values.
For matrices, histc(x,edges) returns a matrix of column histogram counts. For N-D arrays, histc(x,edges) operates along the first non-singleton dimension.
n = histc(x,edges,dim)
operates along the dimension dim.
[n,bin] = histc(...)
also returns an index matrix bin. If x is a vector, n(k) = sum(bin==k). bin is zero for out of range values. If x is an M-by-N matrix, then,
for j=1:N, n(k,j) = sum(bin(:,j)==k); end
To plot the histogram, use the bar command.
