Detailed Description

Demonstration of IgANet function fitting.

This example demonstrates how to implement a simple IgANet to fit a given function on a square geometry. In contrast to the example iganet_fitting.cxx this examples does not make use of pre-computed indices and coefficients and might therefore be slower.

This example can be configured with the following environment variables

IGANET_NCOEFFS - number of B-spline coefficients IGANET_NLAYERS - number of network layers IGANET_NNEURONS - number of neurons per layer IGANET_MAX_EPOCH - maximum number of epochs during training IGANET_MIN_LOSS - tolerance for loss function
