scipy.linalg.blas.ssyr#

scipy.linalg.blas.ssyr(alpha, x, lower=0, incx=1, offx=0, n=None, a=None, overwrite_a=0) = <fblas function ssyr>#

Symmetric rank-1 update a = alpha*outer(x, x) + a (BLAS ssyr).

Parameters:

alphafloat: Scalar multiplier.
xndarray: Input vector.
lowerint, optional: If 0, the upper triangle is used; if 1, the lower. Default is 0.
incxint, optional: Stride between successive elements of x. Default is 1.
offxint, optional: Index of the first element of x to use. Default is 0.
nint, optional: Order of the matrix. Default is inferred from x.
andarray, optional: Symmetric matrix to update; if omitted a new zero matrix is allocated. Default is None.
overwrite_aint, optional: If nonzero, a may be overwritten in place. Default is 0.

Returns:
