Problem extracting values from for loop

F = getdatasamples(y_out.clean,[1:567]);

A = getdatasamples(y_out.simout,[1:567]);

figure(2)

hold on

[RMSE] = rmse(F,A);

plot(passband_frequencies,RMSE)

this is within a forloop and I want to get individual RMSE values for each iteration to plot them against anouther varible I have but I am not sure how to do it

Note that square brackets are a concatenation operator. The colon returns a vector, which you then concatenate with ... absolutely nothing (which what the orange mlint warning is telling you). So instead of this

[1:567]

you just need

1:567

Index the RMSE variable:

for loopIndex = 1 : whatever
    F = getdatasamples(y_out.clean, [1:567]);
    A = getdatasamples(y_out.simout, [1:567]);
    figure(2, 'Name', 'RMSE');
    hold on
    RMSE(loopIndex) = rmse(F, A);
    % Plot (add) a single marker.
    plot(passband_frequencies, RMSE(loopIndex), 'b.', 'MarkerSize', 30);
end
hold off;
% Plot the whole array
plot(passband_frequencies, RMSE, 'b-', 'LineWidth', 3);
grid on;
xlabel('Passband Frequency');
ylabel('RMSE')

I'm not sure what passband_frequencies is (scalar or vector of some length) so you might have to index that inside the loop as well, like

plot(passband_frequencies(loopIndex), RMSE(loopIndex), 'b.', 'MarkerSize', 30);

Yes this worked thank you, and yes i forgot to mention that the passband_frequencies was also a vector
