Owning Class: statistics

Requires: MathScript RT Module

Syntax

n = histogramc(x, edges)

[n, bin] = histogramc(x, edges)

Legacy Name: histc

Description

Counts the number of values that fall between the edges of specified intervals.

Examples

Inputs

Name Description
x Specifies the data values. x is a matrix. If x is a 2D matrix, histogramc performs a column-wise histogram count.
edges Specifies the edges of all intervals. edges is an array. The elements of edges must be in ascending order.

Outputs

Name Description
n Returns the number of values that fall between edges. n is an array of integers. n(i) indicates the number of values in x that fall in the interval [edges(i), edges(i+1)]. -inf and +inf are valid values for edges. n(m) indicates the number of values in x that are equal to edges(m), where m is the length of edges.
bin Returns the bin that contains the corresponding value of x. bin(k) = j indicates that x(k) is in the interval [edges(j), edges(j+1)] when j<m-1, or x(k) = edges(m) when j = m. If bin(k) = -1, x(k) is out of range. bin is an array of integers of the same length as x.
