相关矩阵MATLAB

[poster]

您是否知道一个matlab脚本，该脚本获取一组数据的相关矩阵，例如column = 7的numbe，而row = n >> 7

x1 x2 x3 x4 x5 x6 x7 0.780 2.042 2.754 2.894 5.000 5.000 5.000 0.767 0.816 2.758 2.898 5.000 1.644 1.626 0.816 0.836 1.558 2.124 2.952 5.000 5.000 0.848 0.871 1.588 2.147 2.966 5.000 5.000 1.378 1.620 1.433 2.567 3.268 3.203 5.000 ....

尝试corrcoef 。

通常，您可以通过搜索在线帮助来立即找到这些东西，例如通过便捷的lookfor命令：

>> lookfor correlation corrcoef - Correlation coefficients. msfuncorr - an MS-function which performs auto- and cross- ... >> help corrcoef CORRCOEF Correlation coefficients. R=CORRCOEF(X) calculates a matrix R of correlation coefficients for an array X, in which each row is an observation and each column is a variable. 例如

load file.txt result= CORRCOEF(file);
