[Maxima] Repeated convolution of a continous uniformdistribution

[weaker at directbox.com]

Hi Barton,

thanks for your answer. That is exactly what I was looking for :-)
Now I just have to figure out how to accomplish the loop to do the recursion. *digging up Maxima manual*.

Best regards,

For a possible workaround, try using the variable %z instead of x; thus

 (%i13) f1 : convolution(unit_box(%z),unit_box(%z),%z);
 (%o13) (%z*signum(%z))/2-%z*signum(%z-1)+signum(%z-1)+(%z*signum
 (%z-2))/2-signum(%z-2)

 (%i14) f2 : convolution(f1,f1,%z)$

 (%i15) f3 : convolution(f2,f2,%z)$

 (%i16) plot2d([f1,f2,f3],[%z,0,15]);
