how to write a loop with variable limits

Hi All

I want to write a for loop like :

for j=a:b 
bla bla
end

but I need another loop above this , that check a condition ,and if that condition like(c > 0) is not satisfied , add a certain amount to a and b in a way that , if the first time a=1 and b = 100 , the next one will be : a= 101 and b= 200 and then next one be : a= 201 and b= 300 , and when the condition is satisfied , MATLAB exits the loop add a quantity

Hint:

    while condition == false 
        if not(c>0)
             a = a + something;
             b = b + something;  
        end
        for jj = a : b 
            bla bla
        end
    end

while condition == false

Depends on what you want to achieve. I don't fully understand your question. My hint is kind of pseudo code. Another try:

    while not(c>0)
        a = a + something;
        b = b + something;  
        for jj = a : b 
            bla bla
        end
    end
