I understand that gdsopen is used to create a gds file and also its handle. Following is the command I gave as the input as I want the user unit to be micron and the gds database unit as 5 nm. The resultant error message is ": in gdsopen: argument 2 must be one of scalar matrix"

f = gdsopen('test.gds','1e-6','0.005e-6');

How to assign the unit to each parameter individually?

I do not see any command (other than gdsopen) in the Lumerical script by which the properties for the entire gds file can be modified.
