Evaluating element-wise expressions with PyOpenCl

Similar to PyCUDA, PyOpenCL provides the functionality in the pyopencl.elementwise class that allows us to evaluate the complicated expressions in a single computational pass. The method that realized this is:

   ElementwiseKernel(context, argument, operation, name,",",", 
                          optional_parameters)

Here:

• context: This is the device or the group of devices on which the element-wise operation will be executed
• argument: This is a C-like argument list of all the parameters involved in the computation
• operation: This is a string that represents the operation that is to be performed on the argument list
• name: This is the kernel name associated with ElementwiseKernel
• optional_parameters: These are not important for ...
