median

Median value of fixed-point array

Syntax

c = median(a)
c = median(a,dim)

Description

c = median(a) computes the median value of the fixed-point array a along its first nonsingleton dimension.

c = median(a,dim) computes the median value of the fixed-point array a along dimension dim. dim must be a positive, real-valued integer with a power-of-two slope and a bias of 0.

The input to the median function must be a real-valued fixed-point array.

The fixed-point output array c has the same numerictype properties as the fixed-point input array a. If the input, a, has a local fimath, then it is used for intermediate calculations. The output, c, is always associated with the default fimath.

When a is an empty fixed-point array (value = []), the value of the output array is zero.

Examples

Compute the median value along the first dimension of a fixed-point array.

x = fi([0 1 2; 3 4 5; 7 2 2; 6 4 9], 1, 32)
% x is a signed FI object with a 32-bit word length
% and a best-precision fraction length of 27 bits
mx1 = median(x,1)

Compute the median value along the second dimension (columns) of a fixed-point array.

x = fi([0 1 2; 3 4 5; 7 2 2; 6 4 9], 1, 32)
% x is a signed FI object with a 32-bit word length
% and a best-precision fraction length of 27 bits
mx2 = median(x, 2)
