this is my first post here. I am new to Eigen and do not know if this is the right place to ask this kind of question, so please bear with me.
I intend to use Eigen for some matrix operations in my project. Basically I want to implement some code I previously wrote in Matlab. But I am not sure which would be the right function(s) to use.
In Matlab I have 3 matrix's. A, B and C .
C shall be the linear algebraic product of A and B. C = A*B .
To accomplish the same in my c++ project I used:
MatrixXf A(dim), B(dim), C(dim); // dim = dimension of matrix
Is that the right function for a linear algebraic product ?
Further in Matlab there is the "entry by entry" product. (Array multiplication) " .* "
C = A.*B
What would be the right function for an entry by entry product ?
