What does overlap mean in the case of two functions. Or atleast, what does overlap mean in the case of 2 lines or 2 curves.
Thanks in advance.
The complete sentence to clarify the context:
Convolution is a mathematical operation that takes two functions and measures their overlap. To be more specific, it measures the amount of overlap as you slide one function over another. For example, if two functions have zero overlap, the value of their convolution will be equal to zero. If they overlap completely, their convolution will be equal to one. As we slide between these two extreme cases, the convolution will take on values between zero and one.
