Dear All, is it possible that we convert an object of type Array{Any,1} to an object of type Float64: rb = [0.0 0.0 1.0 1.0] i=1 while i < length(rb) if (rb[i]==rb[i+1]) rb[i+1]=[] global i=i-1 end global i=i+1 end Error: ERROR: LoadError: MethodError: Cannot convert an object…

For efficiency reasons, I’d go the classical way of keeping a Boolean vector of valid indices and indexing into it. function delete_successive(rb) indx = trues(length(rb)) for i = 2:length(rb) indx[i] = rb[i] != rb[i-1] end rb[indx] end rb = [0.0 0.0 1.0 1.0]; ju…

I’m confused as to what you are trying to do. The reason you have a Array{Any,1} is because [] is an empty Vector without a type, and thus of type Any.

I’m confused as to what you are trying to do. Answer: Delete repeated values in the vector.

If you only need the first unique of each value, you can use unique!(rb). EDIT: My alternative method had a mistake.

The corret answer: is rb =[0.0 1.0 ]

[image] Daniel_Berge: unique!(rb) . unique!(rb) ERROR: MethodError: no method matching _unique!(::Array{Float64,2}) You might have used a 2d row vector where a 1d column vector was required. Note the difference between 1d column vector [1,2,3] and 2d row vector [1 2 3]. You can convert to …

You entered a 2 dimension Array, rather than a 1D dimension rb = [0.0 0.0 1.0 1.0] If you want to enter a vector, you need the , rb = [0.0, 0.0, 1.0, 1.0] unique(rb) == [0.0, 1.0]

thanks for your sharing anther method (command in julia) , but If I still want to use own loops in Julia, is it not possible and why we can not archive this simple loop in Julia? rb = [0.0 0.0 1.0 1.0] i=1 while i < length(rb) if (rb[i]==rb[i+1]) rb[i+1]=[] global i=i-1 end globa…

julia> rb = [0.0, 0.0, 1.0, 1.0] 4-element Array{Float64,1}: 0.0 0.0 1.0 1.0 julia> i=1 1 julia> while i < length(rb) global rb if (rb[i]==rb[i+1]) rb = rb[1:length(rb) .!= i] global i=i-1 end global i=i+1 end julia> rb 2-e…

This will skip the duplicates. function removeduplicates(a) y=[a[1]] for i=2:length(a) a[i]!=y[end] && push!(y,a[i]) end y end In Julia, you can’t remove from a vector by rb[i+1]=[]. You can either pop! to remove the last item, or deleteat! to remove a specific index. The…

@Daniel_Berge and @Elrod , Excellent. Thank you!
