Please advise why this is happening with these hyperbola intersections?
The pictures below are the result of the matlab code uploaded which draws and rotates the matlab code to find the intersections of the hyperbolas and therefore TX.
Everything is fone as long as none of the RX have negative values.
This can be seen from the screenshots.
Why is this? Why do the hyperbolas not intersect when negative values are introduced?

"Everything is fone as long as none of the RX have negative values"
It seemd to me that in allyour screen shots at least some of the RX have negative values. In fact the RX are the same in all the shots.
What IS the difference between screener 2 and 3?

I meant TX can have negative values. Sorry about the typo. RX can have negative without any problems.
The TX coordinates are different in each of the screenshots

between RX and TX (typos are easy)

There is nothing wrong with the code. It has been uploaded there so you can check it if you have Matlab.
I can guarantee that no matter what RX or TX values are used whenever eighter or both TX x and y values is a negative number the hyperbolas do not intersect however if TX are all positive then the hyperbolas will intersect. The above screenshots are just examples but this happens everytime. I can guarantee you I have tried a lot of values at this point.

I am sure, but values of what? The RX have not been changed. The TX are output values.

I tried a large number of different TX values. There is no reason to change the RX values.

Does not the program output the TX values. The TX values are what you are looking for. They are not something you make up.

The program is not looking for TX values nor RX values. It is a proof of concept that the hyperbolas intersect at TX. Tx is provided at the start of the Matlab code and can therefore be changed as needed.

"Why do the hyperbolas not intersect when negative values are introduced?"
I don't know that that is a general rule for hyperbolas, or if it just happens that way for your specific examples.
Let's see what others say.
