sortby keywords not supported in eigvals() with Symmetric matrices

[Weiyu-USTC]

I am trying to sort the eigenvalues of a symmetric matrix in a different order. Then with the Symmetric type of matrices, the keyword sortby can work for the function eigen() but not eigvals(). An example:

M = Symmetric([1 2 3; 2 3 4; 3 4 5])
eigen(M, sortby = x -> -x)

The above one-line code can work and output the eigens in descending order:

Eigen{Float64, Float64, Matrix{Float64}, Vector{Float64}}
values:
3-element Vector{Float64}:
9.623475382979782
-7.771561172376096e-16
-0.6234753829797993
vectors:
3×3 Matrix{Float64}:
0.38509 0.408248 0.827671
0.55951 -0.816497 0.142414
0.733931 0.408248 -0.542844

However, for

M = Symmetric([1 2 3; 2 3 4; 3 4 5])
eigvals(M, sortby = x -> -x)

an error shows up:

MethodError: no method matching eigvals!(::LinearAlgebra.Symmetric{Float64, Matrix{Float64}}; sortby=var"#60#62"{typeof(-)}(-))

Can you please format the code a bit more elegantly?

You can use :
```Julia
print("Hello world!")
```
This formats to:

print("Hello world!")

You can use : Julia print("Hello world!") This formats to:

Thanks, done.
