An accumarray function is defined as

A = accumarray(subs,val,sz)

I am running accumarray function in a loop , Is it possible to do

val = val.*another_matrix

inside the accumarray function?

Directly as such, no.

How about a (smallish) example of what you're actually trying to compute? Perhaps an actual example would lead to some alternative methods.

Want to compute this and while loop is called for about 9000 times

while condition 
  val = val.*another_matrix;
  A = accumarray(subs,val,sz)
end
