Help with del2

Could someone try the following code samples?  Probably easiest to start a session and execute 'diary on'. At the end of the session upload the diary file to bug report https://savannah.gnu.org/bugs/index.php?51728.

Sample Code #1:

Does this produce an error because the spacing is neither a scalar nor a vector?

Sample Code #2:

Documentation says the first spacing applies to the first dimension. However, the first dimension is rows, not columns, which is different than specifying the x-separation which people think of as the first argument.

Sample Code #3:

xx = meshgrid (1:5) del2 (exp (xx), 2, 5)

Just making sure they don't something special for the 1-D vectors in Code #2.

Thanks,

Rik
