MATLAB: How to store a signal along with time in the same matrix

matrixvariables

Hello, I want to know how can i store and present two variables in a single matrix. i have a ECG data file of 1×100000 and a time vector of same size. i want to present them in the same matrix. how can i do that? Also can i add other variables too to the matrix like comments etc. Thank you

Concatenate them vertically:

EKG_Record = [time; ECG];

This puts the time vector in row #1 and the electrocardiogram in row #2.

MATLAB: Concatenation or addition of matrix

Try this:

Mcat = [M1 M2];

MATLAB: Unable to perform assignment because the left and right sides have a different number of elements.

Since ecgBR has only one row, not n, you cannot do ecgBR(n, 1), which is the nth row in column 1. But you have 3600 columns, not 1, and 1 row, not 3600. Get rid of the ,1:

for n=5:numel(ecgBR)
    ecg_dif(n)=abs(ecgBR(n)-ecgBR(n-2));
    ecg_dif2(n)=abs(ecgBR(n)-2*ecgBR(n-2)+ecgBR(n-4));
end
