how do i plot a graph after a for loop

so for my assignment i have to plot a graph for deflection angle by angle of attack, however the values for the deflection angle have been calculated using a for loop cycle. how do i plot the results as a single graph?

Store the values in an array and then plot the array.

Depending upon the operations performed in the for loop, you migth be able to vectorize your code as well.

how can i store it in an array?

[Dyuman Joshi]

%% Example
for k=1:number_of_iterations
    %do some calculations
 
    %store the value
    deflection_angle(k) = value_from_calculation;
end

If the size of the final output is known, consider Preallocation.

Also, I recommend you start with the free MATLAB Onramp tutorial to learn the essentials of MATLAB.

Answer 1

[Torsten]

Save the deflection angles in an array and plot after the for-loop.

Answer 2

[Star Strider]

Subscript the variables-of-interest in the loop according to the loop index counter values, and then plot those variables after the loop terminates. They should be vectors and should plot correctly.

Example —

for k = 1:10

x(k) = cos(k);

y(k) = sin(k);

end

figure

plot(x, y)
