I have a while loop inside a for loop. If the condition of the while loop is not satisfied, I want to jump directly to the end of the for loop. Could anyone please help?

t=0:0.5:100;
for i=1:length(t)
while(condition1)
display('Task accomplished')
end %while loop ends here
statement a
statement b
end %for loop ends here
statement c %If condition 1 fails, this is where I want to jump to (directly out of the for loop, irrespective of the value of t)

Statements a and b are necessary in my code to change the condition 1. Hence I want the entire loop to run such that each iteration of the for loop changes the variables in a way that renders condition1 false. As soon as that happens, I'd like to come out of the for loop.
The goal here is still not entirely clear but based on your comment above, as @Rik Wisselink mentioned, it seems like you want a conditional statement in place of the while loop and a while loop in place of the for loop. Does this do what want it to?
t=0:0.5:100;
lengthT = length(t);
i = 0;
while i <= lengthT
if condition1
disp('Task accomplished')
statement a
statement b
i = i+1;
else
break %When condition1 becomes false, here we enter the while-loop
end
end
% We end up here if condition1 becomes false -OR- when i>lengthT
statement c

This is one way to do it.
t=0:0.5:100;
for i=1:length(t)
while(condition1)
display('Task accomplished')
code % do something here to change condition1
end %while loop ends here
if (~condition1)
break
end
statement a
statement b
end %for loop ends here
statement c

If you need statement a/b to change condition1 you need to do that inside your while loop.
I actually just wanted to type a small example, however i noticed that if you want to exit your for loop the moment condition 1 gets false and you change condition 1 inside your while loop, the for loop will only be iterated once.
Maybe you can clarify what you are trying to do?
