-alligned paragraph text+M = OperatorToMatrix(H, ...), takes operator $H$ and returns a matrix representation of this operator $M$. Possible options are 
 +  * M = OperatorToMatrix(H) 
 +  * M = OperatorToMatrix(H,rho) 
 +  * M = OperatorToMatrix(H,psi) 
 +  * M = OperatorToMatrix(H,{psi_1,...,psi_n}) 
 +with rho a density matrix and psi a wave-function.

-===== Input =====+### 
 +For the case there is no density matrix or state given the operator returned is given by the one particle part of $H$. The dimension of $M$ is $H.NF$.

-  * bla : Integer +### 
-  * bla2 : Real +For the case there is a density matrix given as second input the matrix $M$ is given by a mean-field approximated version of $H$. The dimension of $M$ is $H.NF$ and $H.NF$ must be equal to $psi.NF$.

 ### ###
-description text+For the case there is a single state $psi$ given as second input the matrix $M$ is given as an operator on the single Slater determinant basis used for $psi$. The dimension of $M$ is $psi.N$.

-==== Input ==== +### 
-<code Quanty Example.Quanty> +For the case there is a table of states given as second input the matrix $M$ is given by the elements $M_{i,j} = \langle  
--- some example code +\psi_i | H | \psi_j \rangle$. In this case the dimension of $M$ is $n$ with $n$ the length of the table of states.
