Hey, I am a newbie in MATLAB, wanna ask a question: I have a data of frequency (column 1) and the impedance (column 2), and I did multiple measurements, let's say 5 measurements.

I want to plot the graph of the average value of the impedance in each frequency. I tried to find the mean of it, but it turns out that the coding I did find the average of the whole impedance (so i only got 1 average value, it's suppose to be 1 average value for each frequency).

Can somebody help me with the code? I use the .txt files as the data source, by the way.

Thank you for the help.

在 MATLAB Online 中打开

frequency = [1, 2, 3, 4, 5, 6]
impedance = [6  2  7  5  6  7
            10  9  5  1  7  9
             7  8  4  7  4  3
             6  2  4  6  7  2
             2  2 10  4 10 11]
meanImpedance = mean(impedance, 1) % Rows - measurements
plot(frequency, meanImpedance)
