help with cheking rows

if i have a 3 matrix A B and C with dimesion of 400X2 and the first row is the time for all A B C .how can i check if the matrix A, B and C all took place at the same time (i.e. to check that each row of measurements took place at the same time)

I believe you mean first column.

What time format are the time columns in?

Do you want to know specifically if particular rows are not equal, Or do you only need to know if they all are or aren’t equal?

i wanted to know if all the first colum of matrix A B and C are the same and if not rearrage it to be the same .

One way is to use the isequal function.

isequal(A(1,:),B(1,:))
isequal(A(1,:),C(1,:))

If they might only be approximately equal, and not exactly equal, you could test using a tolerance.
