-## Example
-
-```python
-import arrayfire as af
-
-# Display backend information
-af.info()
-
-# Generate a uniform random array with a size of 5 elements
-a = af.randu(5, 1)
-
-# Print a and its minimum value
-af.display(a)
-
-# Print min and max values of a
-print("Minimum, Maximum: ", af.min(a), af.max(a))
-```

+    # Generate uniformly distributed random numers
+    x = af.randu(samples)

 Choosing a particular backend can be done using `af.backend.set( backend_name )`  where backend_name can be one of: "_cuda_", "_opencl_", or "_cpu_". The default device is chosen in the same order of preference.
