Struct Contraction 

pub struct Contraction;

A contraction op: D[mD] = α * op_a(A[mA]) * op_b(B[mB]) + β * op_c(C[mC]).

Implementations

impl Contraction

pub unsafe fn new<'h>( handle: &'h Handle, a: &TensorDescriptor<'h>, modes_a: &[i32], b: &TensorDescriptor<'h>, modes_b: &[i32], c: &TensorDescriptor<'h>, modes_c: &[i32], d: &TensorDescriptor<'h>, modes_d: &[i32], compute_desc: *const c_void, ) -> Result<OperationDescriptor<'h>>

Build a contraction descriptor.

compute_desc is an opaque pointer — pass core::ptr::null() for the library default (compute-type matches C’s dtype).

Safety

compute_desc must be null or a valid cutensorComputeDescriptor_t.

Trait Implementations

impl Debug for Contraction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
