   Dear all,

   I tempting to modify the mask attribute of a transducer object that was created
   before.

   I tempted this:
   transducer1.mask = zeros(Nx, Ny, Nz);
   but:
   

   In class 'kWaveTransducer', no set method is defined for Dependent property 'mask'.  A Dependent property needs a set method to
   assign its value.

   As second step I tempted to understand ho works set and get attribute:
   transducer.get.mask(transducer)
   but:
   No appropriate method, property, or field get for class kWaveTransducer.

   Can somebody to explain me how modify the mask attribute of a transducer object?

   Thank so much

   Hi all,

   was wrote no set method is defined for Dependent property mask,

   I' sorry I did read a set method is defined for Dependent property mask

   :(

   Anyway, thank to anybody that know how to set additional properties and methods for objects of the kWaveTransducer.

   Hi Gg,

   It is not possible to modify the mask property of the k-Wave transducer class (by design). The mask is automatically calculated based on the properties of the physical transducer elements, e.g., the number of elements and their width, length, spacing, etc. If you wish to change the properties of the transducer, you must define a new object of the kWaveTransducer class.

   If you want to define a completely arbitrary source mask, instead of using the transducer, you can directly use pressure and velocity sources as described in the Time Varying Source Problems examples.

   Brad.
