> We use SingularValueDecomposition(RealMatrix) and getSolver() methods.
> This seems to be taking time for large matrices, refer to attached picture.
> Example:925*161
> I have referred to release notes of the library, It seems there are no major changes related to SVD.
>  
> Is there any way to improve performance,
