Forward transform from physical quadrature space stored in inarray and evaluate the expansion coefficients and store in outarray.

Perform a forward transform using a Galerkin projection by taking the inner product of the physical points and multiplying by the inverse of the mass matrix using the Solve method of the standard matrix container holding the local mass matrix, i.e. $ {\bf \hat{u}} = {\bf M}^{-1} {\bf I} $ where $ {\bf I}[p] = \int^1_{-1} \phi_p(\xi_1) u(\xi_1) d\xi_1 $

Inputs:

  • inarray: array of physical quadrature points to be transformed

Outputs:

  • outarray: updated array of expansion coefficients.

Inner product of inarray over region with respect to expansion basis base and return in outarray.

Calculate $ I[p] = \int^{1}_{-1} \phi_p(\xi_1) u(\xi_1) d\xi_1 = \sum_{i=0}^{nq-1} \phi_p(\xi_{1i}) u(\xi_{1i}) w_i $ where $ outarray[p] = I[p], inarray[i] = u(\xi_{1i}), base[p*nq+i] = \phi_p(\xi_{1i}) $.

Inputs:

  • base: an array definiing the local basis for the inner product usually passed from Basis->get_bdata() or Basis->get_Dbdata()
  • inarray: physical point array of function to be integrated $ u(\xi_1) $
  • coll_check: Flag to identify when a Basis->collocation() call should be performed to see if this is a GLL_Lagrange basis with a collocation property. (should be set to 0 if taking the inner product with respect to the derivative of basis)

Output:

  • outarray: array of coefficients representing the inner product of function with ever mode in the exapnsion

Evaluate the derivative $ d/d{\xi_1} $ at the physical quadrature points given by inarray and return in outarray.

This is a wrapper around StdExpansion1D::Tensor_Deriv

Input:

  • n: number of derivatives to be evaluated where $ n \leq dim$
  • inarray: array of function evaluated at the quadrature points

Output:

  • outarray: array of the derivatives $ du/d_{\xi_1}|_{\xi_{1i}} d\xi_1/dx, du/d_{\xi_1}|_{\xi_{1i}} d\xi_1/dy, du/d_{\xi_1}|_{\xi_{1i}} d\xi_1/dz, $ depending on value of dim
