CoopVec<T, N:int>.matMulAccumPacked
Description
Multiply the given input Cooperative vector with the given matrix and accumulate the result into this vector.
Signature
void CoopVec<T, N:int>.matMulAccumPacked<U, PackedK:int>( CoopVec<U, PackedK> input, CoopVecComponentType inputInterpretation, int k, RWByteAddressBuffer matrix, int matrixOffset, CoopVecComponentType matrixInterpretation, CoopVecMatrixLayout memoryLayout, bool transpose, uint matrixStride) where U : __BuiltinArithmeticType where T : __BuiltinArithmeticType; void CoopVec<T, N:int>.matMulAccumPacked<U, PackedK:int>( CoopVec<U, PackedK> input, CoopVecComponentType inputInterpretation, int k, ByteAddressBuffer matrix, int matrixOffset, CoopVecComponentType matrixInterpretation, CoopVecMatrixLayout memoryLayout, bool transpose, uint matrixStride) where U : __BuiltinArithmeticType where T : __BuiltinArithmeticType;
Generic Parameters
U: __BuiltinArithmeticType
PackedK : int
Parameters
input : CoopVec<U, PackedK>
The input Cooperative vector to multiply with the matrix.
inputInterpretation : CoopVecComponentType
Specifies how to interpret the values in the input vector (e.g. as packed values).
k : int
The number of columns in the matrix.
matrix : RWByteAddressBuffer
The matrix buffer to multiply with.
matrixOffset : int
Byte offset into the matrix buffer.
matrixInterpretation : CoopVecComponentType
Specifies how to interpret the values in the matrix.
memoryLayout : CoopVecMatrixLayout
Specifies the memory layout of the matrix (row-major or column-major).
transpose : bool
Whether to transpose the matrix before multiplication.
matrixStride : uint
The stride between matrix rows/columns in bytes.
matrix : ByteAddressBuffer
The matrix buffer to multiply with.
Remarks
Unlike matMulAccum, this function supports packed input interpretations where multiple values can be packed into each element of the input vector. The k parameter specifies the actual number of values to use from the packed input.
