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 <code>kWaveTransducer</code> class. </p> <p>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 <a href="http://www.k-wave.org/documentation/k-wave_time_varying_source_problems.php">Time Varying Source Problems</a> examples.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/modify-the-mask-attribute-of-an-object-transducer-that-was-created-first#post-4854 Sat, 22 Nov 2014 19:14:22 +0000 gigi 4854@http://www.k-wave.org/forum/ <p>Hi all,</p> <p>was wrote <code>no set</code> method is defined for Dependent property mask, </p> <p>I' sorry I did read <code>a set method is defined for Dependent property mask</code></p> <p>:(</p> <p>Anyway, thank to anybody that know how to set additional properties and methods for objects of the kWaveTransducer.</p> <p>Gg </p> http://www.k-wave.org/forum/topic/modify-the-mask-attribute-of-an-object-transducer-that-was-created-first#post-4852 Sat, 22 Nov 2014 17:36:28 +0000 gigi 4852@http://www.k-wave.org/forum/ <p>Dear all, </p> <p>I tempting to modify the mask attribute of a transducer object that was created<br /> before.</p> <p>I tempted this:<br /> <code>transducer1.mask = zeros(Nx, Ny, Nz);</code><br /> but:<br /> <pre><code>In class &#39;kWaveTransducer&#39;, no set method is defined for Dependent property &#39;mask&#39;. A Dependent property needs a set method to assign its value.</code></pre> <p>As second step I tempted to understand ho works set and get attribute:<br /> <code>transducer.get.mask(transducer)</code><br /> but:<br /> <code>No appropriate method, property, or field get for class kWaveTransducer.</code></p> <p>Can somebody to explain me how modify the mask attribute of a transducer object?</p> <p>Thank so much<br /> Gg </p>
