matlab - Avoid counters in loops with mathematician rule -

i'm trying find mathematician formula avoid counter increment 1 step step loops (any number first element, last element , increment).

example 1 (one loop):

min=first element, max=last element , hop=increment (variable i)

with counter:

c = 1; = min:hop:max     c = c + 1; end 

without counter:

for = min:hop:max     c = floor((i-min)/hop) + 1; end 

example 2 (two loops):

mini=first element, maxi=last element , hopi=increment (variable i)

minj=first element, maxj=last element , hopj=increment (variable j)

with counter:

c = 1; = mini:hopi:maxi     j = minj:hopj:maxj         c = c + 1;     end end 

without counter:

for = mini:hopi:maxi     j = minj:hopj:maxj         x = (floor((i-mini)/hopi)+1);         y = (floor((j-minj)/hopj)+1);         c = x*y+(x-(floor((maxi-mini)/hopi)+1))*((floor((maxj-minj)/hopj)+1)-y);     end end 

any simplification c formula 2 loops?

any formula find c k loops, c(k)?
