plot in designated subfigures in loops

I have the following code. I want to plotsubfigures as required in the comments in main.m. How to plot in designated subfigures in such loops below?

% main.m
tiledlayout(2,3)
for i=1:2
    for j=1:3
        function myfun;
    end
end
    
% myfun.m
plot % in subplot(1,j)
plot % in subplot(2,j)

You can use tiledlayout and nexttile to create a tiled chart for multiple layouts.

Refer to the documentation for more information and assiciated examples at:

• https://www.mathworks.com/help/matlab/ref/tiledlayout.html
• https://www.mathworks.com/help/matlab/ref/nexttile.html

For your case, I tried with a dummy myfun function as:

function myfun(i, j)
    % Generate a sine wave with varying frequency and amplitude
    x = linspace(0, 2*pi, 100);
    frequency = i; % Frequency increases with i
    amplitude = j; % Amplitude increases with j
    y = amplitude * sin(frequency * x);

    % Calculate the tile index based on i and j for a 2x3 layout
    tileIndex = (j-1) + (i-1)*3 + 1;
    
    % Plot in the appropriate subplot
    nexttile(tileIndex);
    plot(x, y); % Plot the sine wave
    
    % Customize the plot
    title(sprintf('Freq: %d, Amp: %d', frequency, amplitude));
    xlabel('x');
    ylabel('sin(x)');
end

Now using the main.m script, as you are suggesting, you can plot in designated 'subfigures':

tiledlayout(2,3) % Create a 2x3 grid of tiles
for i=1:2
    for j=1:3
        myfun(i, j); % Call myfun with row (i) and column (j) indices
    end
end

This demonstrates how to use nested loops and the tiledlayout with nexttile to create complex subplot arrangements.

Hope it helps!
