Its either fast or convinient or some balance between them. In this case
you seem to want performance, which means you will have to give up
convinience: in this case you should try not to create class that will
just hold 2D array - using function calls to get access to one value is
not exactly performance friendly.
You also use jagged arrays - if you have fixed number of rows and
columns, then its efficient to access it like you do, say here is faster
version:
for(int i = 0; i<rowcount*colcount; i++)
{
a[i] = (b[i] + c[i] + d[i] + e[i] + f[i])/2.5; // <--- consider
getting rid of floating point math, its not as fast as integers
}
This avoids 2nd loop as well as less calculations to access value, this
is of course based on the fact that you access your array from top to
bottom, left to right.
