I agree that this is a good way of solving this problem.
Here is another way. Instead of defining a vector of uni-dimensional
functions and trying to integrating
each component (a uni-dimensional function), we can do something below
return(f[x,k]) ## use matrix to represent the sequence of uni-dimensional
my.integral<-function(k) ## k=1,...,5000 denotes the function labels
When calculating the integrals, just perform
This is a way of avoiding loops but the computing time needs to be carefully
