Does Optim not support function optimization with matrix variables?

I want to optimize my function with Optim, but something went wrong . I have written an example. Does this example show that optim.jl does not support functions whose variables are matrices?If not, what should I do about it? using Zygote using Optim using RecursiveArrayTools function get_f(A)   M=reshape(1:16,4,4)   U=exp(A)   T=UMU’   return tr(T) end function my_function()   A0=zeros(4,4)   results=optimize(get_f,VectorOfArray([A0])) end my_function() And the…
