## USAGE:

    z = gsw_z_from_depth(depth)

## DESCRIPTION:

    Calculates height, z, from depth.

    Note. Height z is NEGATIVE in the ocean. i.e. Depth is -z.
     Depth is not used in the GSW computer software library.

## INPUT:

    depth  =  depth                                                    [ m ]

## OUTPUT:

    z  =  height                                                       [ m ]
    Note. At sea level z = 0, and since z (HEIGHT) is defined to be
      positive upwards, it follows that while z is positive in the
      atmosphere, it is NEGATIVE in the ocean.

## EXAMPLE:

    depth = [   10;   50;  125;   250;  600; 1000;]

    z = gsw_z_from_depth(depth)

    z =
       -10
       -50
      -125
      -250
      -600
     -1000
