Why does matlab exe fail with mapped drive path as input?

I have a matlab script with a path and filename as inputs.

The matlab script runs fine within within the matLab development environment, i.e.:

ret = get_TIA_TC_T0_darkV_R0('c:/ZMI4200/MatLab Exes/', 'ZY24130009')

or passing in a mapped drive as the 1st argument:

ret = get_TIA_TC_T0_darkV_R0('y:\', 'ZY24130009')

In both cases the matlab script executes with no issues:

The script has been compiled into an exe.

from a cmd window window with admin privileges if a call the routine:

 get_TIA_TC_T0_darkv_R0 "c:/ZMI4200/MatLab Exes/" "ZY24130009"

I get the desired output.

If I instead used a mapped drive ("y") with access to the same files i.e.:

 get_TIA_TC_T0_darkv_R0 "y://" "ZY24130009"

I see the following:

Output argument "success" (and possibly others) not assigned a value in the execution with "get_TIA_TC_T0_darkV_R0" function.

Is there a problem with the mapped drive path length (75 chars)?

To check:

Did you try

 get_TIA_TC_T0_darkv_R0 "y:\" "ZY24130009"
