Try e.g., <code>chmod 755 kspaceFirstOrder-CUDA</code>.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/h5readc-error-when-using-kspacefirstorder2dg#post-8326 Wed, 13 Oct 2021 17:18:40 +0000 Yanfei Xiang 8326@http://www.k-wave.org/forum/ <p>Hello praveenbalaji,</p> <p>I met same problem (pasted belov) as you described above when I used MATLAB R2019a to run some codes related k-Wave toolbox, I want to inqury have you find the solution ?
