In this article the attempt to show a role of computer mathematics in the modern industry of radio-electronic measurement is made. The main task of modern measuring technique is the research of environmental processes and also different structures and systems based on them and their parameters as well. For getting clear results it’s necessary to use electronic data processing. Theoretical research and projecting methods for devices and systems and the mathematical modeling of their work play very important role. In these cases the computer mathematics is widely used. The author of the article describes in a very detail its work making examples of the work of different devices.
