ABSTRACT
MATLAB is one species of numerical-values calculation and graphic tools software which is widely used to apply at research institutions at present. The particularities are: concise grammar-structure、highly efficient in numerical values plete function of graphs、especially it is adapted to evildoing professional programmer to plish the tasks that are numerical-values calculating and scientific experiments treating. The ancient methods of measured data-processing need establishing special proceedings of treating matrices operation, moreover, it plex and greatly difficult.
This article introduces one programming method dealing with leveling and measuring work based on MATLAB. Compared with other algorithm language, it has particularities which are simply programming and quickly operating. The article separately expatiate the theories basics、realizing steps and running results at leveling and measuring work. With the analysis of examples, it has prodigious application value in measured data-processing by use of MATLAB. Moreover, it shortens programming time and improves working effectiveness.
Key words:MATLAB;work;measuring work;programming
