hi everybody Is it possible to do a signed rank wilcoxon test for two sample with different sizes ?

x=[331 308 300 414 253 323 452 396 104];
y=[248 393 260 355 279 184 386 450 432 196 197];
[p,h,stats] = signrank(x,y,'tail','right')

and error is : SIGNRANK requires the data vectors to have the same number of elements. sorry if the answer is obvious!

I think you probably actually want the ranksum command.

The signed rank test that you are using is specifically for paired measurements.
