Error using Operator/ in Vector and FullMatrix

[Raghunandan Pratoori]

Hello team,

I am trying to use the following equations -

        r = r/theta;

OM = OM_1*cos(theta);

where r is a dealii::Vector<double>, theta is double, OM and OM_1 are dealii::FullMatrix<double>.

According to the documentation, operator/ and operator* are implemented for both Vector and FullMatrix, but both throw an error "no match for 'operator'".

I am using v9.3.0 and have included /lac/vector.h and /lac/fullmatrix.h. I believe I am missing something trivial. Can anyone identify what mistake I might be making?

Thanks in advance,

Raghunandan.

Hi Raghunandan,

I think that you misinterpreted the documentation: operator/= is implemented for the Vector class and operator*= is implemented for the FullMatrix class. So your code probably needs to be

r /= theta;

OM *= cos(theta);

I hope that this helps you resolve your issue.

Best,

Jean-Paul
