I have the following questions about the package SymEngine.jl (running with julia 1.5.2 on a linux machine).

(1) List of SymEngine.jl functions for linear algebra computations with symbolic matrices. For example, reduced row echelon form, determinant, transpose, etc

Also, how does one get help on using the above functions at the julia command line?

(2) List of SymEngine.jl simplification functions for  
simplifying symbolic expressions containing trigonometric terms, etc
