i would like to know if there is an equivalent of Matlab in C++ with the Eigen library. I mean if i have this vector in Matlab :
A = [1 2 5]
And i ask to Matlab to return exp(A) Matlab will answer me this :
exp(A) = [exp(1) exp(2) exp(5)]
Do you know if there is something of equivalent in C++ with the Eigen library ?
