matlab - A system or language to reverse equations? -


lets have simple equation follows:

x = 50 * (20 * item)

is there system or language reverse automatically? lets have x input , want find out item is.

item = (x - 50) / 20

a trivial , misleading example, illustrate point. i'm not talking solving equations least squares fitting or such, instead system can reverse equations generating have code hand. i'm not mathematician forgive incorrect terminology (if any).

a colleage of mine said matlab can natively. has idea how? can specify inputs have , output i'm looking for? or have use inbuilt math functions handwritten reversed equation?

you're looking http://www.mathworks.com/help/symbolic/solve.html

you should first declare symbolic variable: syms item , then: solve(x == 50 * (20 * item), item) should give you're looking for.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
