Module matrix_functions 

Matrix functions: exponential, logarithm, and square root.

Provides GPU-accelerated matrix function computations via PTX kernel generation:

• Matrix Exponential (expm): Scaling and squaring with Padé approximation. Computes e^A for a square matrix A.
• Matrix Logarithm (logm): Inverse scaling and squaring with Padé approximation. Computes log(A) for a matrix with eigenvalues in the right half-plane.
• Matrix Square Root (sqrtm): Denman–Beavers iteration. Computes A^{1/2} such that sqrtm(A) * sqrtm(A) = A.

Each plan struct generates self-contained PTX kernels using KernelBuilder/BodyBuilder from the oxicuda-ptx crate.
