MATLAB: For loop saving a vector, not a value

for loopFuzzy Logic Toolbox

if i had

x = -10:0.1:10;
f1 = trapmf(x,[-2 0 0 2]);

how do i save the (x, f1) values of each iterations using the for loop?

I'm thinking it starts with something like

for 
    i = 1:length(x)
    a = x(i);
    b = f1(i);
end

but this will only give me a & b to be 1 value not a vector of length(x)

How about

for i = 1:length(x)
      a(i) = x(i);
      b(i) = f1(i);
end

if you wanted/needed to assign a and b via a "for" loop?

You need to tweak your code just a bit:

x=0:360;
for k1 = 1:length(x)
    y(k1) = cosd(x(k1));
end
plot(x,y)

You have to address every element of ‘x’ separately in each iteration of the loop, and store every value calculated in vector ‘y’. Use the same value of the index variable in each vector.

MATLAB: Loop: stop if value repeats

N = Number; 
G = Guess;
x = 1:N;
R = nan(1, N);
found = N;
for k = 1:N
  R(k) = mod(G^x(k), N);
  if any(R(1:k-1) == R(k))
      found = k;
      break
  end
end
R = R(1:found)
