The rationale for this inversion of terminology is the same as [the rationale for SPIR-V](a2-01-spirv-target-specific.md#matrix-type-translation). Since the WGSL matrix multiplication convention is the normal one, where inner products of rows of the matrix on the left are taken with columns of the matrix on the right, the order of matrix products is also reversed in WGSL. This is relying on the fact that the transpose of a matrix product equals the product of the transposed matrix operands in reverse order. + +## Explicit Parameter Binding + +The `[vk::binding(index,set)]` attribute is respected when emitting WGSL code, and will translate to `@binding(index) @group(set)` in WGSL. + +If the `[vk::binding()]` attribute is not specified by a `:register()` semantic is present, Slang will derive the binding from the `register` semantic the same way as the SPIRV and GLSL backends.
