Detailed Description

Median.

Returns the median of the values in an array. If size is even, then the mean of the size/2 and size/2+1 element is the median.

If an optinal mask is given, values only on those locations that correspond to true values in the mask are used.

Example

vec = (/ 1.,2.,3.,4.,5.,6.,7.,8.,9.,10. /)
! Returns 5.5
out = median(vec)

See also example in test directory.

Parameters

[in]	real(sp/dp) :: vec(:)	1D-array with input numbers
[in]	logical, optional :: mask(:)	1D-array of logical values with size(vec). If present, only those locations in vec corresponding to the true values in mask are used.

Return values

real(sp/dp) :: out

Median of values in input array
