`GroupedTransforms.jl` provides the following fast algorithms:

- nonequispaced fast transformation with exponential functions for grouped index sets based on the NFFT (non-equispaced fast Fourier transform)

- nonequispaced fast transformation with cosine functions for grouped index sets based on the NFCT (non-equispaced fast cosine transform)

## Getting started

In Julia you can get started by typing

```julia

] add GroupedTransforms

```

then checkout the [documentation](https://nfft.github.io/GroupedTransforms.jl/stable/).
