The RCX is based on the 8-bit Renesas H8/300 microcontroller, including 32 KB of ROM for low-level IO functions, along with 32 KB of RAM to store high-level firmware and user programs.The RCX is programmed by uploading a program using a dedicated infrared interface. I went through some answers in the community and I saw people saying this command: matlab -nodisplay -r "functionname (argument1, argument2, argumentN);exit" But what is "matlab" at the beginning?
