ERROR: MethodError: no method matching zero(::Type{Any})
1
I am very new to Julia. I am trying to solve a system of nonlinear equations to find a vector (p_new). Below a simplified version of my problem. The issue is that I get this message: "ERROR: MethodError: no method matching zero(::, Type{Any})". I am not sure whether it is because the initial conditions are not well defined. Thanks in advance!
p_1 = [ 1, 2, 2.3]
p_1b = [ 1, 2.2, 2.5]
mgc = [1, 1, 0.5]
theta = 0.8
OW1 = [0 1 0; 1 1 1; 0 0 1]
g = ones(3,1)
function pupdate!(p_1,mgc,theta,OW1)
delt = p_1.*theta
delt = 2.718281828459.^delt
Sp1 = sum(delt)
sp1 = delt./Sp1
markup = p_1 .- mgc
sp1 .= markup
end
g0 = [p_1b, mgc, theta, OW1]
p_new = nlsolve(pupdate!, g0)

Also you should put spaces around.*and./. In general you do not usenlsolvecorrectly. I would recommend you to read the examples in github.com/JuliaNLSolvers/NLsolve.jl to see what should be passed as arguments to this function. If you would still have problems please edit your question writing in mathematical terms (not in code) what optimization problem you want to solve and I can help you to implement it.
