Description Lauri Berkovits 2017-03-02 08:25:09 UTC 
I tried to change my old Eigen 3.2.x into latest stable release 3.3.3. 
This code

    const float c = 1.234;
    MatrixXcf C  =  c*MatrixXcf::Ones(5,5).triangularView<Lower>();

leads to compilation errors ("no match for operator*, template argument deduction/substitution failed etc.."). This can be easily worked around:

    // this is OK:
    MatrixXcf A  = MatrixXcf::Ones(5,5).triangularView<Lower>();
    MatrixXcf C  = c * A;

so I am not sure if this is bug or intented behavior.
