I have a nested function d_1 that i'm trying to run for the values 1-10. I need to store the data so i can plot it.

I tried d_1(1:10) but this is just displaying a single value (1)

would a for loop work for this?

something like:

N = 10

x = zeros(length(N))

for d_1 =

I'm lost from here, any pointers or help would be appreciated.

Could you elaborate on this?

I will try my best, I'm slowely getting it to work.

right now i have

N = 10;
for k = 1:N
    d_1(k)
end

this displays the answers i need in the command window, but i need each one of these answers stored in a row vector so i can plot them.

i believe i figured it out

N = 1:10;
s = zeros(1,length(N));
for k = 1:length(N)
    s(k) = d_1(k)
end
plot(s)

Hi @Matthew,

I understand that you want to run the nested function 'd_1' for the values 1-10 and store the data for plotting.

You can use a loop to iterate over the values and store the results in an array. Here is an example script:

% Initialize an empty array to store the data
data = [];
% Iterate over the values 1-10
for i = 1:10
    % Call the nested function and store the result in the array
    data(i) = d_1(i);
end
% Now you can plot the data
plot(1:10, data)
xlabel('x')
ylabel('d_1(x)')
% Define the nested function d_1
function result = d_1(x)
    % Your nested function logic here
    result = x^2; % Just an example, replace with your actual logic
end
