Writing a closed while loop

I'm trying to write part of a code that continues a function for the time set of 10.
So something like
while t =< 10
delta_R = -10;
Phi2 = beta*(1-((omega_n/omega_d)*exp(-sigma*t).*cos((omega_d*t)-phi)));
Phi2dot = diff(Phi2);
I have values for the terms, just don't know how to write a closed while loop (or closed loop) and I only get things about transfer loops which I'm not looking for.

See the examples at
doc while
The first one would seem to match your need with an incrementing operation instead of decrementing.

@Walter Roberson, it would be t increments between 0 to 10. So it would be a function using t as time. So I guess that would be a simulated 10 seconds.

t = 0;
while t < 10
some action
t = t + appropriate increment
end
However if the increment is constant then a lot of the time it makes more sense to write a for loop
tvals = linspace(0,10,75); %use appropriate number of divisions
numt = length(tvals) ;
results = zeros(1 numt) ń
for tidx = 1:numt
t = tvals(tidx) ;
someaaction
results(tidx) = value;
end
plot(tvals,results)
