[docs]@rfm.simple_test class numpy_ops_check(rfm.RunOnlyRegressionTest, pin_prefix=True): '''NumPy basic operations test. `NumPy <>`__ is the fundamental package for scientific computing in Python. It provides a multidimensional array object, various derived objects (such as masked arrays and matrices), and an assortment of routines for fast operations on arrays, including mathematical, logical, shape manipulation, sorting, selecting, I/O, discrete Fourier transforms, basic linear algebra, basic statistical operations, random simulation and much more. This test test performs some fundamental NumPy linear algebra operations (matrix product, SVD, Cholesky decomposition, eigendecomposition, and inverse matrix calculation) and users the execution time as a performance metric. The default assumption is that NumPy is already installed on the currest system. ''' executable = 'python' executable_opts = [''] descr = 'Test NumPy operations: dot, svd, cholesky, eigen and inv'
