Hi,
How to use openmp in Eigen for OOPs, since I'm a beginner in C++[https://eigen.tuxfamily.org/dox/TopicMultiThreading.html] is not sufficient to understand, for me.
My requirement is as follows ,

#include <eigen3/Eigen/Core>
#include <eigen3/Eigen/Dense>
#include <eigen3/Eigen/Eigenvalues>
#include <eigen3/unsupported/Eigen/MatrixFunctions>


Class "****" {

funct1();
funct2();
........

};

funct1(){
MatrixXcd A(3,3);
MatrixXcd B(3,3);
MatrixXcd C(3,3);

for(int i(0); i < N, i++){
B << .......... << endl;//(typedef entries .....)
A += B;
C *= A.exp();
}
return pow(abs(C(0,1)),2);
}

int main(){
****.........


funct1();

}


how to do parallel computation, kindly tell me what to and how to do.........

best,
sadashiv

Heyho,

a) your function does not return anything. What do you want to caluclate?

b) For your very small system of three 3x3 matrices does not need openmp.
