        # PyNUFFT: Python non-uniform fast Fourier transform
        
        A minimal "getting start" tutorial is available at http://jyhmiinlin.github.io/pynufft/ .
         
        ## Installation
        
        $ pip install pynufft --user
        
        ## How to use?
        
        ### Using Numpy/Scipy
        
        ```
        $ python
        Python 3.6.11 (default, Aug 23 2020, 18:05:39) 
        [GCC 7.5.0] on linux
        Type "help", "copyright", "credits" or "license" for more information.
        >>> from pynufft import NUFFT
        >>> import numpy
        >>> A = NUFFT()
        >>> om = numpy.random.randn(10,2)
        >>> Nd = (64,64)
        >>> Kd = (128,128)
        >>> Jd = (6,6)
        >>> A.plan(om, Nd, Kd, Jd)
        0
        >>> x=numpy.random.randn(*Nd)
        >>> y = A.forward(x)
        ```
        
        ### Using PyCUDA
        
        ```
        >>> from pynufft import NUFFT, helper
        >>> import numpy
        >>> A2= NUFFT(helper.device_list()[0])
        >>> A2.device
        <reikna.cluda.cuda.Device object at 0x7f9ad99923b0>
        >>> om = numpy.random.randn(10,2)
        >>> Nd = (64,64)
        >>> Kd = (128,128)
        >>> Jd = (6,6)
        >>> A2.plan(om, Nd, Kd, Jd)
        0
        >>> x=numpy.random.randn(*Nd)
        >>> y = A2.forward(x)
        ```
        
        ## Testing GPU acceleration
        
        ```

        >>> from pynufft import tests
        >>> tests.test_init(0)
        device name =  <reikna.cluda.cuda.Device object at 0x7f41d4098688>
