Hello community,

I want to bootstrap the residuals of a simple OLS regression, i.e. generate 1000 draws of my residuals. I am using fitlm and my code is:

OLS=fitlm(x,Y)

res=OLS.Residuals.Raw;

resboot = bootstrp(1000,[],res)

But when I run this, my resboot matrix is empty.

What am I doing wrong? I just want to obatain a 1000 different draws of my residuals with replacement
