Hi everyone,
I'm not good in c++ and I need some help on this.
I have a function let's say Foo like:

Code: Select all

MatrixXd* Foo(dim1, dim2)
{
MatrixXd* X = new MatrixXd::Random(dim1, dim2);
return X;
}


This function doesn't work and gives me error. How can I return such a thing?
Thank you so much.

MatrixXd::Random is a function, not a MatrixXd! You first need to allocate and then assign:

Code: Select all

MatrixXd* X = new MatrixXd(dim1, dim2);
X->setRandom();


Thanks for the quick reply.
