For loop or while loop? help please

Dear sir,

I have a simple code

for k=1:3

    for i=1:7

do something

    end
end

If k=1 I would like the loop to execute the body from i= 1 to 7 if k=2 or k=3 I would like the loop to execute the body from i = 1 to 6.

How can I do that please? I don't want to repeat the body in the if condition. Thank you very much

Kind Regards

S

[Azzi Abdelmalek]

m=7
for k=1:3
if k>1
   m=6
end
for i=1:m
   do something
end
end

%or

for k=1:3
   for i=1:7-(k~=1)
      %do
  end
end

or

for k=1:3
  if k==1, 
      iMax = 7 
  else 
      iMax = 6
  end
  for i =1:iMax
    do something
  end
end

in this case you can change it such that if you do need to vary the iMax you can change the condition.
