I am trying to find array indexes in which a certain value is found.
For example, I have the next array with 10 elements.
A = [2 4 6 8 10 12 14 16 18 20]
Now, I have a value x = 11.
According to x value, I would like to get the indexes 5 and 6 corresponding to the array values 10 and 12, in which 11 is found.
I tried to solve it as next:
However, it returns an empty vector.
I hope you can help me.
Thank you very much!
