About Matrix4x4 in QML

arkceajin

Hi, I am learning the Qt 3D module. I found the Qt.matrix4x4 provide different API than QMatrix4x4 in C++ side (by using F1 check the API doc).
look likes Qt.matrix4x4 don't have such scale or rotation ... operations. even not in autocomplete.

BUT! these functions do exist!

var m = Qt.matrix4x4(1, 0, 0, -0.5, 0, 1, 0, 0, 0, 0, 1, 0.5, 0, 0, 0, 1)
m.scale(2)
console.log(m)
// qml: QMatrix4x4(2, 0, 0, -0.5, 0, 2, 0, 0, 0, 0, 2, 0.5, 0, 0, 0, 1)

https://doc.qt.io/qt-5/qmatrix4x4.html vs https://doc.qt.io/qt-5/qml-matrix4x4.html

So Why??? And the type is QMatrix4x4...
