Creating Bootstrap samples in MATLAB

I am confused about how the bootstrap samples are generated, are these values taken from the original data or some random numbers? I have variable (a) of length 700 i.e. 700 samples and I am trying to produce 100 bootstraps of 'a' and compare these 100 bootstraps with another variable (b). I am trying to use the bootstrp function of MATLAB to do this. Bootstat= bootstrp(100,@corr,a,b); Is this correct? If so, the 100 bootstraps generated will contain any random numbers or numbers from the original variable 'a'? Please help me understand this process.

Thanks a lot!

Did you read the help of function bootstrp and about bootstraping in general? No additional random sample values are generated, instead bootstraping is based on random selection of existing values. – NoDataDumpNoContribution Jun 19 '17 at 20:24
Yes thank you. I understand it better now. – user8020776 Jun 20 '17 at 13:21
