Bootstrapping default intensities

Hi,

I'm quite a beginner with MATLAB and I'm wondering if someone can help me with this problem: I have the term structure of cds (maturities and spreads)and the term structure of zero coupon bond rates (rates and maturities)and I need to bootstrap the default intisities, which are assumed to be a deterministic function of time and piecewise constant, from a cds pricing reduced form model assuming continuous payments. What MATLAB code should I write to do this? I know there's a proper function called cdsbootstrap but unfortunately it isn't provided in the release I have.

Thanks a lot.

if you have the statistics toolbox you can use bootstrp()

Isn't the bootstrap function used only to bootstrap interest rate curves? How can I use it to find default intensities given my initial inputs?
