Hi,
I have a single data (50 numbers) set which I just want to re-sample through Bootstrap. The problem is the bootfun part as it asks for a function, I do not want to do any sort of analysis on the data. Just resample it, the matlab help section says to use [] for the bootfun, if no function is needed. So far it isn't working.
Maybe there is afunction I could use, but I do not need one considering I just have 50 data samples and nothing to compare with.

you need to have 2 assignments to get the resampled data
>> r = 1 + 2.*randn(25,1);
>> [x,bootsamp]=bootstrp(25,[],r);
>> whos bootsamp
Name Size Bytes Class Attributes
bootsamp 25x25 5000 double

@proecsm: I'm impressed. You found the problem without seeing the original code driven by the description "it is not working". Fine. +1
