Does a median of all images in X. The value reject can be used to exclude a value to be taken when calculating the median.
result = cubemedian(X [, reject])
|X:||A matrix or a FITS file name. If a FITS file name is given, the global variable tmpmem determines how many bytes of data are read in at a time.|
|reject:||Optional, a value which should be discarded.|
If reject is given and no pixel along the cube is different from reject, a value of 0 will be inserted.
