In this case, <code>source.p</code> is indexed as <code>(source_point_index, time_index)</code>, where the <code>source_point_index</code> corresponds to a particular element in <code>source.mask</code> following MATLAB's column-wise linear matrix indexing. </p> <p>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 <code>source.p = reshape(source.p, Nx*Ny*Nz, Nt);</code></p> <p>There's some more information in section 3.4 of the <a href="http://www.k-wave.org/documentation.php">k-Wave manual</a> that you might find helpful.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/questions-about-the-source#post-4532 Thu, 22 May 2014 02:25:26 +0000 cge 4532@http://www.k-wave.org/forum/ <p>Hello All</p> <p>Is it possible to make the source.p a function of (x,y,z,t)?<br /> I mean besides the time, it is also a function of location<br /> in the K-wave? </p>
