Types

The expected type of each function argument is indicated in this reference. Here is a list of these types:

int integer value
hobj a handle for any getfem++ object.
scalar scalar value
string string
ivec vector of integer values
vec vector
imat matrix of integer values
mat matrix
spmat sparse matrix (both matlab native sparse matrices, and getfem sparse matrices)
precond getfem preconditioner object
mesh mesh object descriptor (or gfMesh object)
mesh_fem mesh_fem object descriptor (or gfMeshFem object)
mesh_im mesh_im object descriptor( or gfMeshIm object)
mesh_slice mesh_slice object descriptor (or gfSlice object)
const_mesh non-modifiable mesh object (mesh and mesh_fem can be used everywhere a const_mesh is required)
cvstruct convex structure descriptor (or gfCvStruct object)
geotrans geometric transformation descriptor (or gfGeoTrans object)
fem fem descriptor (or gfFem object)
eltm elementary matrix descriptor (or gfEltm object)
integ integration method descriptor (or gfInteg object)

Arguments listed between square brackets are optional. Lists between braces indicate that the argument must match one of the elements of the list. For example 

[X,Y]=dummy(int i, {'foo' | 'bar'} [,vec v])

means that the dummy function takes two or three arguments, its first being an integer value, the second a string which is either 'foo' or 'bar', and a third optional argument. It returns two values (with the usual matlab meaning, i.e. the caller can always choose to ignore them).
