Unfortunately, plotting is only currently supported for disc elements in 3D, and arc elements in 2D. </p> http://www.k-wave.org/forum/topic/kwavearrayplotarray-rectangular-element-type-not-recognized-v14#post-8667 Wed, 16 Nov 2022 17:52:47 +0000 scottschoenjr 8667@http://www.k-wave.org/forum/ <p>MATLAB R2020b<br /> Windows 10.0.19044<br /> k-Wave 1.4</p> <p>Following definition of a linear array with kWaveArray.addRectElement, the .plotArray method returns an error that "rect is not a valid array element type."
