   Hello All

   Is it possible to make the source.p a function of (x,y,z,t)?
   I mean besides the time, it is also a function of location
   in the K-wave?

   Hi cge,

   It is possible to define a separate source signal for each point in your source mask (rather than a single time series). In this case, source.p is indexed as (source_point_index, time_index), where the source_point_index corresponds to a particular element in source.mask following MATLAB's column-wise linear matrix indexing.

   If you define the source mask to cover the entire grid, you could define source.p as a function of (x, y, z, t), and then reshape it using source.p = reshape(source.p, Nx*Ny*Nz, Nt);

   There's some more information in section 3.4 of the k-Wave manual that you might find helpful.

   Brad.
