cat map function to scramble a one dimentson sequence

因子分析可在许多变量中找出隐藏的具有代表性的因子。将相同本质的变量归入一个因子，可减少变量的数目，还可检验变量间关系的假设。(Factor analysis can be found in many variables hidden with a representative factor. The same nature of the variables included in a factor, can reduce the number of variables, but also to test the relationship between the hypothesis.)
