"""

ArrayFire is a high performance scientific computing library with an easy to use API.

>>> # Monte Carlo estimation of pi

>>> def calc_pi_device(samples):

# Simple, array based API

# Generate uniformly distributed random numers

x = af.randu(samples)

y = af.randu(samples)

# Supports Just In Time Compilation

# The following line generates a single kernel

within_unit_circle = (x * x + y * y) < 1

# Intuitive function names

return 4 * af.count(within_unit_circle) / samples

Programs written using ArrayFire are portable across CUDA, OpenCL and CPU devices.

The default backend is chosen in the following order of preference based on the available libraries:

1. CUDA

2. OpenCL

3. CPU

The backend can be chosen at the beginning of the program by using the following function

>>> af.set_backend(name)

where name is one of 'cuda', 'opencl' or 'cpu'.

The functionality provided by ArrayFire spans the following domains:

1. Vector Algorithms

2. Image Processing

3. Signal Processing

4. Computer Vision

5. Linear Algebra

6. Statistics
