Hi

I am new to eigen and trying to use it using Visual Studio 2008. I have taken the VectorXd as member variable in one class but compiler gives this error .

Any idea why ?


error C2039: 'YOU_CALLED_A_FIXED_SIZE_METHOD_ON_A_DYNAMIC_SIZE_MATRIX_OR_VECTOR' : is not a member of 'Eigen::internal::static_assertion<condition>'

My code looks like this

Code: Select all

class A
{

private:
VectorXd  m_Paramters;  // This causing the compiler error
}

Your error must come from another line of code.

Hi

Yes i fixed the problem but still it is strange.

In class i initialized function like that.

m_Paramters = VectorXd(numberOfParameters);
m_Paramters.fill(0);

When i changed it to
m_Parameters = VectorXd::Zero(numberOfParameters);

Error gone but it doesn't producing error in every time.
In some classes first code is working I donot know why.
