I want to combine real and complex signals into a vector (or bus). But neither the Selector nor BusCreator was able to combine these data types into a vector. I would like to know why and if there are blocks to do that before I use real-imag to complex block.
In Simulink there are blocks that handle complex numbers.
Open the Simulink Library browser and in the search box on the top toolbar, search for complex, you will see those blocks.
