Hi,
 
I have a 7000x7000 matrix, and each element is an integer. For each element, I want to apply the function :
 
wt <- 0
 for(q in 1:count){
 wt <- wt + 0.5^(q-1)
}
 
I get the value of 'count' from the elements in the matrix , and want to store the corresponding 'wt' value for that element.
 
I suppose I could loop through the matrix, and apply the function to each element but this would take a really really long time. Are there any quicker ways to get the same result?
 
many thanks,
 
Tim
