I am trying to merge arrays like this:
If:
a = [1.2, 1, 3, 4]
b = [0.0 , 0.0]
c = [0.0 , 0.0]
a = a + b + c
Then the result should be:
[0.0 , 0.0 , 1.2 , 1 ,3 ,4 , 0.0 ,0.0]
what I do is that extract histogram of array and merge it with normal array.
x1, bins, patch = plt.hist(array1, bins = round(max(array1) - min(array1)))
x1 = b + x1 + c
but the form of x1 is
x1 = [ 2. 0. 0. 1. 0. 2. 5. 0. 1. 1. 0. 1. 5.]
and maybe that cause the error like this
ValueError: operands could not be broadcast together with shapes (5,) (30,)
please help me. I don't know what to do
You could use np.concatenate to to do this but you can also do this by converting your arrays to lists.
import numpy as np
a = list(np.array([1.2, 1, 3, 4]))
b = list(np.array([0.0 , 0.0]))
c = list(np.array([0.0 , 0.0]))
D= a + b + c
So in you code try:
x1 = list(b) + list(x1) + list(c)
#Put it back into a numpy array
x1 = np.array(x1)
