However, some speedup techniques possible in spectral methods due to their tensor-product character are no longer available.

Such an approach is called a spectral method.

Does not result in dense linear systems like spectral methods do (see also Gaussian grid).

Scaled correlation should be in many cases preferred over signal filtering based on spectral methods.

The presented algorithm is non iterative and thanks to the use of spectral methods has a short computing time.

Implemented on a computer using numerical approximations, this is known as the spectral method.

We can solve the differential equation in the coordinate basis, using a spectral method.

There are many possible choices for (one possibility leads to the spectral method).

These are not to be confused with spectral methods.

Some problems in mixture model estimation can be solved using spectral methods.
