我有2个数字，分别为1或-1。 Matlab上有哪些标准工具可以帮助我计算两个向量之间的相关数？提前致谢！

您需要的是CORRCOEF (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/corrcoef.html)函数：
R = corrcoef(vector1(:),vector2(:)); %# Returns a 2-by-2 matrix of %# correlation coefficients 如果您具有统计工具箱 (http://www.mathworks.com/access/helpdesk/help/toolbox/stats/) ，则可能还需要检出CORR (http://www.mathworks.com/access/helpdesk/help/toolbox/stats/corr.html)函数：
RHO = corr(vector1(:),vector2(:)); %# Returns the linear correlation coefficient %# (default is a Pearson correlation)
