Traditional computer language syntax complex, requiring the programmer has a high level of programming. MATLAB as a new computer language is simple to learn, the code short and efficient, powerful computing, etc., is increasingly being accepted by the majority of engineering and research personnel. the mathematical theory of least squares method for the determination of the lattice parameter, and how to use MATLAB programming to achieve the accurate determination of the lattice parameter was measured lattice parameters LaNi5 hydrogen storage alloy and use self procedure results with existing literature provide data are in good agreement, to prove that the program has a high practical value.
