## Name

VkCooperativeMatrixPropertiesNV - Structure specifying cooperative matrix properties

Loading… please wait.

## C Specification

The `VkCooperativeMatrixPropertiesNV` structure is defined as:

    // Provided by VK_NV_cooperative_matrix
    typedef struct VkCooperativeMatrixPropertiesNV {
        VkStructureType      sType;
        void*                pNext;
        uint32_t             MSize;
        uint32_t             NSize;
        uint32_t             KSize;
        VkComponentTypeNV    AType;
        VkComponentTypeNV    BType;
        VkComponentTypeNV    CType;
        VkComponentTypeNV    DType;
        VkScopeNV            scope;
    } VkCooperativeMatrixPropertiesNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `MSize` is the number of rows in matrices A, C, and D.

- `KSize` is the number of columns in matrix A and rows in matrix B.

- `NSize` is the number of columns in matrices B, C, D.

- `AType` is the component type of matrix A, of type VkComponentTypeNV.

- `BType` is the component type of matrix B, of type VkComponentTypeNV.

- `CType` is the component type of matrix C, of type VkComponentTypeNV.

- `DType` is the component type of matrix D, of type VkComponentTypeNV.

- `scope` is the scope of all the matrix types, of type VkScopeNV.

## Description

If some types are preferred over other types (e.g. for performance), they should appear earlier in the list enumerated by vkGetPhysicalDeviceCooperativeMatrixPropertiesNV.

At least one entry in the list must have power of two values for all of `MSize`, `KSize`, and `NSize`.

Valid Usage (Implicit)

- VUID-VkCooperativeMatrixPropertiesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_COOPERATIVE_MATRIX_PROPERTIES_NV`

- VUID-VkCooperativeMatrixPropertiesNV-pNext-pNext
  `pNext` must be `NULL`
