IgnoredBufferElementType

Parameters

input : CoopVec<U, K>

The input cooperative vector to multiply with the matrix.

inputInterpretation : CoopVecComponentType

Specifies how to interpret the values in the input vector (e.g. as 8-bit integers, 16-bit floats, etc).

matrix : RWByteAddressBuffer

The matrix to multiply with the input vector.

matrixOffset : int

Byte offset into the matrix buffer.

matrixInterpretation : CoopVecComponentType

Specifies how to interpret the values in the matrix (e.g. as 8-bit integers, 16-bit floats, etc).

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 in bytes between rows/columns of the matrix.

matrix : ByteAddressBuffer

The matrix to multiply with the input vector.

matrix : RWStructuredBuffer<IgnoredBufferElementType, DefaultDataLayout>

The matrix to multiply with the input vector.

matrix : StructuredBuffer<IgnoredBufferElementType, DefaultDataLayout>

The matrix to multiply with the input vector.

Return value

A new cooperative vector containing the result of the matrix multiplication.
