Numerical experiments of the adjoint PAT with under-sampled sensors. The behaviors of Time-Reversal (TR), Back-Projection (BP), and Truncated Back-Projection (TBP) reconstruction are demonstrated.
The following problems occurred in the process of running the code,and how should I solve it?
Thank you very much
Error using gpuArray/ndgrid
Out of memory on device. To view more detail about available memory on the GPU,
use 'gpuDevice()'. If the problem persists, reset the GPU by calling
'gpuDevice(1)'.
