float3x2 Structure
[Some information relates to pre-released product which may be substantially modified before it's commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here.]
A 3x2 matrix, used for 2D transforms.
This matrix type uses a row vector layout. The x and y of this matrix's translation vector correspond to the fields m31, m32.
This type is only available in C++. Its .NET equivalent is System.Numerics.Matrix3x2.
