I am using Python 3.6 in Anaconda3 Spyder IDE.
I have two arrays:
X Y Z
0 0 0
2.059801 0 0
-1.203126 3.402953 0
-1.108639 -1.567853 2.715601
-0.938564 -1.32733 -2.299003
0.4283375 0.91755 0.208299
and want to subtract the value of the value of each column or the array
a_c from the each value in the corresponding column of array c.
Trying a_mm = a - a_c where a_mm is the new array results in the error
ValueError: operands could not be broadcast together with shapes (3,5) (1,3)
My search for a solution has not been successful.
