The authors, after a short reminder of one pattern's structure, stress on the possible double approach of relations uniting the variables of this pattern: use of fonctions, what is within the mathematical analysis sphere, use of linear algebra profiting by matricial calculation's development and automatiosation. They precise the respective interests on these methods, their bounds and the imperatives for utilization, according to the kind of variables, of data, and the objective for work, understanding phenomenons or helping towards decision.
作者在简要回顾了一种模式的结构后，强调了连接该模式变量的关系可能存在的双重方法：使用函数（这属于数学分析领域），利用矩阵计算的发展和自动化的线性代数。他们根据变量的类型、数据以及工作目标（理解现象或辅助决策），明确了这些方法各自的优势、局限性以及使用的必要性。
