store repetitive data results

I can't really explain what i want to do, but i will try my best. I have an repetitive form(for) that for every input value it returns an answer after doing a set of operations. What i want is to store every answer into an string that at the ending of all calculations contains all the answers. Sorry but i'm kind new to MATLAB so please be gentle with me. Thanks.

Give an example?

[Pavel]

if true
  for thet=0:5:180; 
  a=1;
  b=0;
  c=-5*r^2+2*r^2*sind(thet)*sind(thet)+2*r^2*((4-5*sind(thet)*sind(thet)+sind(thet)*sind(thet)*sind(thet)*sind(thet))^(1/2));
d=[a b c];
e=roots(d);
out=e(e>0)
end
i want every out answer stored into an string.

Answer 1

[Andrei Bobrov]

r = 100;
th = 0:5:180;
c = -5*r^2+2*r^2*sind(thet).^2+2*r^2*((4-5*sind(th).^2+sind(th).^4).^(1/2));
x = cell(numel(th),1);
for jj = 1:numel(th)
    rt = roots([1 0 c(jj)]);
    x{jj} = rt(rt>0);
end

Thank you very much

Answer 2

Like this?

cellArrayOfStrings  = cell(numberOfRuns, 1);
for k = 1 : numberOfRuns
  cellArrayOfStrings{k} = SomeFunctionThatReturnsAString(k)
end

SomeFunctionThatReturnsAString() would be some function you write that returns some output argument as a string.

Answer 3

    clc
r=100;
x=cell(90,1);
for k=1:90;
for thet=0:5:180; %unghiul elementului conduc?tor
    a=1;
    b=0;
    c=-5*r^2+2*r^2*sind(thet).^2+2*r^2*((4-5*sind(thet).^2+sind(thet).^4)^(1/2));
d=[a b c];
v=0:5:180;
e=roots(d);
out=e(e>0);

end

x{k}=out(k)

end

i get the following error when i execute the code: "Attempted to access out(2); index out of bounds because numel(out)=1."
