Hi @Vinicio,

I see that you are working on setting up a cellular network site and transmitter configuration for a multi-sector cell simulation in MATLAB, but you have encountered the error: “Incorrect number or types of inputs or outputs for function location.”

After reviewing your code, it seems that this error arises because the code is currently using a "geopoint" object as an input to the "location" function, which actually expects a "txsite" object.

To resolve this, you can modify the centerSite definition to use "txsite" instead of "geopoint", as shown below:

centerSite = txsite('Name', 'center', 'Latitude', -5.895806113892169, 'Longitude', -38.62032597572306);

Here is the attached output with the above adjustment for your reference:

Refer to the following documentations for more details about the functions:

1. location: https://www.mathworks.com/help/comm/ref/txsite.location.html
2. txsite: https://www.mathworks.com/help/comm/ref/txsite.html

Hope this solves your query.
