Vector of vector re-size
Vector of vector re-size
So I have two vector of vectors like:
matchings_vec = VectorVectorVectorVectorAny(num_tilt1)
Minfoall_vec = VectorVectorVectorVectorVectorVectorFloat64(num_tilt1)
I defined it as:
matchings_vec = [VectorAny() for i in 1:num_tilt1]
Minfoall_vec = [VectorFloat64() for i in 1:num_tilt1]
Then I am trying to resize the inner vectors like:
for tt = 1:num_tilt1
t_tt = t[tt] #; t1 = t_tt; t2 = 1;
if t_tt == 1
num_rot1 = 1
else
num_rot1 = round(Int, num_rot_t2 * t_tt/2)
if rem.(num_rot1, 2) == 1.0
num_rot1 += 1
end
num_rot1 /= 2
end
num_rot1 = round(Int, num_rot1)
#resize!(matchings_vec[tt], num_rot1)
matchings_vec[tt] = VectorAny(num_rot1)
#resize!(Minfoall_vec[tt], num_rot1)
Minfoall_vec[tt] = VectorFloat64(num_rot1)
for rr = 1:num_rot1
num_tilt2 = round(Int, num_tilt2)
#resize!(matchings_vec[tt][rr], num_tilt2)
matchings_vec[tt][rr] = VectorAny(num_tilt2)
#resize!(Minfoall_vec[tt][rr], num_tilt2)
Minfoall_vec[tt][rr] = VectorFloat64(num_tilt2)
for tt2 = 1:num_tilt2
t_im2 = t[tt2]
#t_im2_1 = t_im2; t_im2_2 = 1;
if t_im2 == 1
num_rot1_2 = 1
else
num_rot1_2 = round(Int, num_rot_t2 * t_im2/2)
if rem.(num_rot1_2, 2) == 1.0
num_rot1_2 += 1
end
num_rot1_2 /= 2
end
num_rot1_2 = round(Int, num_rot1_2)
#resize!(matchings_vec[tt][rr][tt2], num_rot1_2)
matchings_vec[tt][rr][tt2] = VectorAny(num_rot1_2)
#resize!(Minfoall_vec[tt][rr][tt2], num_rot1_2)
Minfoall_vec[tt][rr][tt2] = VectorFloat64(num_rot1_2)
end
end
end
I am getting this error:
MethodError: Cannot convert an object of type ArrayFloat64,1 to an
object of type Float64 This may have arisen from a call to the
constructor Float64(...), since type constructors fall back to convert
methods.

Can you suggest what I am doing wrong? Thanks!
num_tilt2
Float64
VectorAny(num_tilt2)
VectorAny(0.0)
VectorAny([0.0])
VectorAny
VectorFloat64
Hi @ColinTBowers, Sorry I edited it and getting the error above

I think you think that
VectorAny(num_rot1) creates a vector of length num_rot1. It doesn't. As per my comment above, it will throw an error if num_rot1 is Int or Float64 (this is a deliberate design choice). Just use something like zeros(Float64, num_rot1) to initialize a VectorFloat64 of length num_rot1. Also, I don't know why you're bothering with all the resizing. As near as I can tell, you could remove every resize! line and still get the same outcome.– Colin T Bowers

What is
num_tilt2? It seems to just appear out of nowhere in the example code you provide. I'm guessing it is of typeFloat64and so the error is caused byVectorAny(num_tilt2), because Julia doesn't automatically convert scalar types to arrays. SoVectorAny(0.0)will cause an error, butVectorAny([0.0])will not (although I'm not sure why you would specifically want aVectorAnywhen you could have aVectorFloat64... it isn't clear to me what you're trying to do with this code)– Colin T Bowers
