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