how can i save the results of multiple executions?

hello

if i have the fallowing situation

t=0.1:1:10

for t-ang=t*pi/18

function that depend on t-ang

then i plot the result of this function with the t-ang

end

so the function execuited periodically for each value of t and plot each case.

but it only give me the last value of the fuction by overwriting previous results how can i save the results of each value

for t-ang=t*pi/18

... does that mean you are calculating

syms t ang
ANG = simplify(solve(t-ang == t * sym(pi) / 18, ang))

ANG =

You should learn this pattern:

tvals = 0.1:1:10;
num_t = numel(tvals);
results = zeros(num_t,1);
for t_idx = 1 : num_t
    t = tvals(t_idx);
    value = some calculation in t;
    results(t_idx) = value;
end
plot(tvals, results)

When you use this pattern, the entries in tvals do not need to be sorted or equally spaced or unique. In some cases where those do happen to be the case, you can abbreviate the code. For example,

results = zeros(10,1);
for K = 1 : 10
    value = some calculation in (K-0.9);
    results(K) = value;
end
