Analysis of behaviour in sports through polar coordinate analysis with MATLAB®

The use of the polar coordinates technique (Sackett, Exceptional Infant Psychosocial Risks in Infant-Environment Transactions, 1980; Anguera, Establecimiento de pautas para la viabilidad de la categorización y reducción de datos en los marcos de conducta mediante la técnica de coordenadas polares, 1985) helps estimating the kind of the relation existing between a focal category and the remaining categories that make up the taxonomic system. Nowadays, there is no software application in the market capable of conducting the polar coordinates analysis and, consequently, it tends to be carried out in a rather unsystematic way. Given the need to systematise, facilitate and speed up the procedure, a software application called CoordenadasPolares.m was developed, this being an script file for execution in MATLAB® (The MathWorks, Inc., http://www.mathworks.com/), which performs a polar coordinates analysis of the input data for a given category and represents the relations of activation and inhibition between the behaviours on a vector map.
