MATLAB: Two variables in while-loop

while loop

I'm supposed to sum up the numbers

and figure out how many joints are needed for the sum to be bigger than 0.9977? I've figured out this much:

But the task says that it must be solved with the while-loop. And I do not get this when I have two variables, k and n. How do I put it into this:

? Please help me understand, I have really tried, but I'm new to both the subject and matlab.

k = 0;
while sum < value
 k = k + 1;
 sum = ...
end

We recommend against naming a variable sum, due to the conflict with the very-often used sum() function. You should get into the habit of deliberately not naming variables sum: if you do not, then you are quite likely to end up with code that tries to use sum as a variable but also tries to use sum as a function.

You can have them enter some value that indicates when to quit, like if x or temp is negative of something

if x < 0
  break;
end

if temp(1) < 0 || temp(2) < 0
  uiwait(warndlg('Exiting loop because you entered a negative number'));
  break;
end

MATLAB: Save While-loop to vector

Change it to the following:

VelocityVector=[];
while Velocity2>=-20
Velocity2=hastighet(acceleration(0,m,g),t,v0,t0);
VelocityVector=[VelocityVector; Velocity2];
 Height2=hojd(acceleration(0,m,g),t,h0,v0,t0);
   t=t+dt;
end

Then all your data is saved in VelocityVector.
