Your question is so riddled with false assumptions, that it is difficult to know how to address it.
If it is "programming space" that you are short of, then you need to consider minimising the amount of machine code ( and constants embedded in it ), that your program gets compiled to. The program variables are in RAM and don't consume the same flash memory that the program occupies. However, the initialisation of them does.
The length of the names of your variable names, function names, or any other user-defined keywords makes no difference, because they are generally not present in the final linked and compiled code. Likewise, the length of your numerical constants, as expressed in source code/text form, doesn't matter.
If you want to find out how various code formulations affect the executable program size, there is nothing stopping you from doing your own experiments. You will need to use the correct language for the environment you are compiling for, however. Is it Matlab code, that you have written there ? Matlab is usually an interpreted, not compiled, language.
