Composable Kernel includes template utilities for creating vector types with customizable widths. These template utilities also flatten nested vector types into a single, wider vector, preventing the creation of vectors of vectors.
Vectors composed of supported scalar and custom types can be created with the ck::vector_type template.
For example, ck::vector_type<float, 4> creates a vector composed of four floats and ck::vector_type<ck::half_t, 8> creates a vector composed of eight half-precision scalars.
For vector operations to be valid, the underlying types must be either a :doc:`supported scalar type <Composable_Kernel_supported_scalar_types>` or :doc:`a custom type <Composable_Kernel_custom_types>` that implements the required operations.
