Hello.. I am writing a matlab code for ecg signal processing. Here I get many intermediate results like R peak values, R peak locations, R-R distances, QRS width etc for each ecg in an ecg file. All these results are 1*x vectors. I want to combine all of them and display in a single matrix of say x*y at the end for easy analysis of all the results. ie, each row should represent different parameters like peaks, locetions, RR distance, QRS width, etc and each column should represent the sample number/time instances. Is it possible to achieve this? Can anybody tell me how can i do this? ( I hope my doubt is clear to you all.) Thank you.

在 MATLAB Online 中打开

E.g.,

R_values = 1 x X vector of peak values
R_locations = 1 x X vector of peak locations
R_distances = 1 x X vector of distances
etc
R = [R_values; R_locations; R_distances; etc]'; % an X x Y matrix of results

The single quote ' is a complex conjugate transpose, while the period and single quote .' is a non-conjugate transpose. It is a good habit to use the non-conjugate transpose unless you specifically need a complex conjugate transpose for some linear algebra.

You can read more about the complex conjugate transpose here:
