Hello, 
Subject: exceeds matrix dimensions,undefined function From: Matt Fig Date: 20 Mar, 2009 19:54:02 Message: 2 of 11 
n better be an mbyn matrix if you are requesting the element n(x,y). Both x and y also should be positive integers with x<=m and y<=n.

it is an m by n matrix and both are positive integers. n is a number that is calculated at row x and column y position. So it is not a function

I dont quite get your point. n(x,y) is one value that is determined at an image pixel location of x,y and so are the other values determined for that pixel location. I know rho and theeta_incident i have to find n(x,y).

yes i know rho and theeta_incident... yes i can choose the appropriate value but the thing is how do i get those values... I am using the paranthesis to make it easy for myself.. so u r suggesting that i use ''roots'' and then ''solve''?

I have tried solving it mathematically and i can not solve it. ofcourse using pen and paper. So if this can not be factored out you mean to say it can not be solved?:S
