I need some ideas/advice on how to code the following:
I have two random numbers which are generated and are related to each other (representing x and y co-ordinate). These random numbers are generated within a specified range: (-range, +range).
I want to categorize these values in a (2-dimensional) grid. The grid size is not definite and so can be varied by the user would be in the order of 400 x 400. (e.g., think CCD detector). For each random number pair (x, y) I want to store a hit (a plus one) in the corresponding grid reference.
In the order of 500,000 related random numbers (x and y) are to be generated and the position recorded according to grid reference. So code needs to be fast.
any ideas/advice? much appreciated.
