Please help me, I do not understand this sentence in vector mathematics

[physicophysiology]

Would you explain this sentence in detail?

More context would have been interesting.

While you could use equation 1.100 with complex numbers (the mathematics is fine) it doesn’t make sense in the context that we don’t see - only real values are meaningful.

You must provide more detail about the context of the passage you quoted. What situation is "the geometric situation being described"?
