Matrix4x4.CreateTranslation The result is flipped over?

[Coloryr]

I try to create a Matrix4x4

Matrix4x4.CreateTranslation(300, 300, 0);

the value is

{{ {M11:1 M12:0 M13:0 M14:0}
 {M21:0 M22:1 M23:0 M24:0}
 {M31:0 M32:0 M33:1 M34:0}
 {M41:300 M42:300 M43:0 M44:1} }}

but i saw some doc say it should be

{{ {M11:1 M12:0 M13:0 M14:300}
 {M21:0 M22:1 M23:0 M24:300} 
{M31:0 M32:0 M33:1 M34:0}
 {M41:0 M42:0 M43:0 M44:1} }}

It's just a different order, see https://en.wikipedia.org/wiki/Row-_and_column-major_order
In case of .NET, it's column-major order here.

.NET is rather row-major, not column-major. Hence why the translation appears sequentially in the W row, not the W column.

This matches how most other languages and CPU side vector/matrix math libraries operate including GLM (OpenGL Math Library) and DXM (DirectX Math Library).

GPUs typically default to column-major (although you can customize this in GLSL, HLSL, SPIR-V, etc) and so its typical to have to Transpose the matrix prior to uploading it to the GPU.
