Numpy arrays: element-wise operations Element-wise operation Operation that is repeated for each element of an array and does not depend on previous/next elements. e.g. x exact;i = e sin(t i) 8i2[0;N 1] Could be done with a for loop: for i in range(N): x exact[i] = np.exp( np.sin( t[i] ) ) But is computationally faster with numpy vector syntax:

The product operation is deÞned by C i,j =! k A i,k B k,j. (2.5) Note that the standard product of two matrices is not just a matrix containing the product of the individual elements. Such an operation exists and is called the element-wise product or Hadamard product , and is denoted as A " B .

NumPy performs a fast element-wise subtraction of two arrays: In [27]: b - a Out [27]: array([2, 6, 10]) When the shapes of the two arguments are not the same, but share a common shape di-mension, the operation is broadcast across the array. In other words, NumPy expands the arrays such that the operation becomes viable:

NumPy operations return views or copies. Views share the underlying storage of the original array. Changing the values of a view will change the original and vice versa. Read the documentation to determine if an operation returns a copy or a view. Most operations return a view when possible and a …

The element-wise operators in NumPy are known as Univer-sal Functions, or ufuncs. Many of the methods of ndarray simply invoke the corresponding ufunc. For example, the ... guarantee that a one-sided operation will complete before the data segment it accessed is used by another process. mpi4py mpi4py is a Python wrapper around MPI. It is ...
