Singular value decomposition for mlx arrays

Note that mlx's svd returns "full" SVD, with U and V' both square matrices. This is different from R's implementation.

Usage

# S3 method for class 'mlx'
svd(x, nu = min(n, p), nv = min(n, p), ...)

Arguments

x

An mlx matrix (2-dimensional array).

nu

Number of left singular vectors to return (0 or min(dim(x))).

nv

Number of right singular vectors to return (0 or min(dim(x))).

...

Additional arguments (unused).

Value

A list with components d, u, and v.
