Why is bootci not terminating?

I am trying to bootstrap my data to find confidence intervals. My code is as follows:
N=10; f = @(x) fitLifeTimesBoot(microtime, Gsm1,gammakin,bkgfrac,x); [ci,bootstat] = bootci(N,f,kinburst);
It just recalculates endlessly, instead of the 10 times specified by nboot (for testing). If I switch my code to the following it works fine:
N=10; f = @(x) fitLifeTimesBoot(microtime, Gsm1,gammakin,bkgfrac,x); [bootstat] = bootstrp(N,f,kinburst);
However, I want to get out the confidence intervals, not just the matrix of bootstrapped values. What am I doing wrong?

The default bootci 'type' is bca. This requires doing a jackknife and it can take a long time if the number of data rows is large. Try one of the other types and see if that makes the problem go away.
