Hi i have a mex file that has the following line in it

currentcell = 1* *(y+((rows*counter1) + counter2);

it is called quite a few times 200K plus

can anyone tell me what the 1* part signifies ( i built my mex file using matlab example files so i have included it but i dont know what it does) as my code runs far slower when i take it off (yet still correctly) why is this the case? to me it looks like its a multiplier of 1 but im pretty sure im wrong !

Cheers

What are the declarations for the other variables, in particular y?
