MATLAB: Spearman correlation in Matlab!

Question

Hey Matlab users,

If I have two series of data:

a = [1 4 6 3 4 6 7 8]; b [34 56 34 56 79 23 48 28];

and I want to perform a Spearman correlation what would be the proper command in MATLAB? I need both p-value and RHO.

Thanks for your help.

Hi, If you have the Statistics Toolbox.

a = [1 4 6 3 4 6 7 8]; 
b = [34 56 34 56 79 23 48 28];
[RHO,PVAL] = corr(a',b','Type','Spearman');
