Matrix object constructor?

konstantin_shiriazdanov

I woiuld like to create a 2d rotation matrix and would like it to support all matrix specific operations like multiplication and others. And i cant find any matrix constructor function taking 2x2 array and giving matrix object, analogically as we have vector() function.
Currently as workaround I had to use RotationMatrix3d() and wordToPlane()

You can create a matrix by adding the type tag to the appropriate data structure:

[[0, 1], [2, 3]] as Matrix

...but you're right that it would be more consistent to have a matrix() function which does this, as we have with vectors. Seems to me like a simple oversight, and we can add that function to the standard library in a future release. Thanks!

thanks, @kevin_o_toole_1, it's all because I'm too used to the type of the expression is determined by the external function
