This study aims at developing an artificial neural network OceanANN in MATLAB to recover missing wave data. The program OceanANN was designed friendly to the user for their convenient and useful interfaces. Based on the Levenberg-Marquardt algorithm, OceanANN was established with 1 input - layer, 2 hidden - layers and 1 output - layer. Each hid...
