function CC_trap(X::Array{Float64,2}, tag::Int64)
a = 0.0
for i=1:size(X)[1]
for j=1:size(X)[2]
global a += weights_CC[i]*X[i,j]
end
end
a = result_integral*Parameters.dv[tag]
end
But I’m getting the error
syntax: global a: a is a local variable in its enclosing scope
There are global variables in your code. This is the way to make the function compile.
function CC_trap(X::Array{Float64,2}, tag::Int64)
a = 0.0
global weights_CC
global Parameters
for i=1:size(X)[1]
for j=1:size(X)[2]
a += weights_CC[i]*X[i,j]
end
end
a = result_integral*Parameters.dv[tag]
end
However, I have some doubts about using global variables in the first place. They rarely lead to efficient (type-stable) code. Usually they can be avoided, and it is worthwhile to think about ways in which that could be done. It usually leads to a better design.
