Ensure argument `x` is a 1-D C-contiguous array. Returns ------- value : ndarray A 1-D C-contiguous array.

Re-wrap a cuSPARSE CSR result in ``self``'s csr_container. cuSPARSE's gemm helpers always return a ``csr_matrix``; if ``self`` is a s

Helper function for atleast_nd functions.

Copied from _compute_size_by_dict in numpy/core/einsumfunc.py Computes the product of the elements in indices based on the dictionary idx_dic

Copied from _find_contraction in numpy/core/einsumfunc.py Finds the contraction for a given set of input and output sets. Parameters ---

Copied from _flop_count in numpy/core/einsumfunc.py Computes the number of FLOPS in the contraction. Parameters ---------- idx_contr

Wraps get_index_dtype: arrays never downcast (check_contents is disabled for sparray instances).

Number of stored values, including explicit zeros. Subclasses override this to provide format-specific counts. Public access is via :

Small n x n identity with int64 indices.

Default: convert to CSR. Format subclasses override.

Default matrix-vector multiplication handler.

Convert a tuple of coordinate arrays to a (..., ndim)-shaped array.

Convert a tuple of coordinate arrays to a (..., ndim)-shaped array.

Configure axes argument for an n-dimensional FFT. The axes to be transformed are returned in ascending order.

Reshape input array to 1-D

r""" Raise a degree of a polynomial in the Bernstein basis. Given the coefficients of a polynomial degree `k`, return (the co

Default implementation of _rmatvec; defers to adjoint.

Enhanced version of _run_1d_filters that uses correlate1d as the filter function. The params are a list of values to pass to the get_weights

Sets value at each (i, j) to x Here (i,j) index major and minor respectively, and must not contain duplicate entries.

Calculate various forms of windowed FFTs for PSD, CSD, etc. This is a helper function that implements the commonality between the stft,

Transpile the statement. Returns (Data): The CUDA code and its type of the expression.

Common input validations for generate_knots and make_splrep.

Atomically write pre-encoded (hash + cubin) data to the cache dir. Unlike :meth:`save`, this method accepts data that is already in the

Change a transfer function from the variable `z` to `z**-1`. Parameters ---------- num, den: 1d array_like Sequen

Create a view into the array with the given shape and strides. .. warning:: This function has to be used with extreme care, see notes.

Upcasts matrix to a floating point format. When the matrix has floating point type, the method returns itself. Otherwise it makes a c

Take a slice along axis 'axis' from 'a' and set it to 'b' in-place. Parameters ---------- a : numpy.ndarray The array to be slice

Builds a sparse array/matrix from sparse sub-blocks Args: blocks (array_like): Grid of sparse objects with compatible shapes.
