is there any faster way to operate a group of statements in a loop only once, than applying if else

for .........
statemets 1;
statements 2:
if iteration == 0
[value1,value2] = function(args1,args2); %dependent on statment 1 and 2
statement 3;%dependent on statement 1 and 2
statement 4;%dependent on statement 1 and 2
end
other statements;
end

Yes, you can unroll.

[value1,value2] = function(args1,args2);
statement 1;
statement 2;
for iteration = ....     %same bounds as before because you still want other statements to be done for the initial iteration
  other statements;
end

Unrolling is still the answer.

statements 1;
statements 2:
[value1,value2] = function(args1,args2); %dependent on statment 1 and 2
statement 3;%dependent on statement 1 and 2
statement 4;%dependent on statement 1 and 2
other statements;

for iteration = 1 : ...     %skip the first iteration where iteration = 0
  statemets 1;
  statements 2:
  other statements;
end
