gf_geotrans

The geometric transformation must be used when you are building a custom mesh convex by convex (see the add_convex() function of mesh): it also defines the kind of convex (triangle, hexahedron, prism, etc..)

# Calling Sequence

    GT = gf_geotrans(string name)

## Description

General constructor for geotrans objects.

The geometric transformation must be used when you are building a custom mesh convex by convex (see the add_convex() function of mesh): it also defines the kind of convex (triangle, hexahedron, prism, etc..)

## Command list

- `GT = gf_geotrans(string name)`

  The name argument contains the specification of the geometric transformation as a string, which may be: - GT_PK(n,k) : Transformation on simplexes, dim `n`, degree `k`. - GT_QK(n,k) : Transformation on parallelepipeds, dim `n`, degree `k`. - GT_PRISM(n,k) : Transformation on prisms, dim `n`, degree `k`. - GT_PRODUCT(A,B) : Tensorial product of two transformations. - GT_LINEAR_PRODUCT(geotrans gt1,geotrans gt2) : Linear tensorial product of two transformations
