matrix method Random not in documentation
Hello, just realised that in the machine learning example there is an initialisation method Random(a,b) void OnStart () { matrix mat1( 3 , 3 ); mat1.Random(- 1.0 , 1.0 ); Print (mat1); } that does not appear in the matrix Initialisation chapter of the reference and does not even appear
