I get the error message below, and cannot find any sign of the cause.
With debug statements, I found that its dying trying to call a function
with the signature
function
linsolve{T<:Operator,N<:Number}(A::Vector{T},b::Array{N};tolerance=0.01,maxlength=1000000)
...
end
Any thoughts? Maybe its a bug in Julia?
TypeError: subtype: expected Type{T}, got Tuple{TypeVar,TypeVar}
