I am updating some code from v0.6 to v1, and I have not been able to resolve one particular issue (except by workaround). In v0.6 my code included the construction
A[:,(A[1,:].==1) & (A[2,:].==10)]
for selecting the parts of the array A (of type Array{Int64,2}) based on the conjunction of two conditions. When I try to run this code in v1, I get the error message
MethodError: no method matching &(::BitArray{1}, ::BitArray{1})
followed by a suggestion for correcting the error, which I have been unable to implement. I would greatly appreciate assistance. Thanks.
