median
Median value of fixed-point array
Syntax
c = median(a)
c = median(a,dim)
Description
c = median(a)a along
its first nonsingleton dimension.
c = median(a,dim)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)
