DXSpiral is a toolkit for spiral waves in a disk, on a polar grid. The primary purpose is calculation of response functions (critical eigenmodes of the adjoint linearized operator), but the toolkit includes other components which can be useful independently. Principal algorithms are described in Phys Rev E 79:056702, 2009 by the above authors. More details are in README and dxdoc.pdf.
