Hi. I have a question. I need to create a MATRIX of this type (nx2): A=[1 1; 1 2; 1 3;1 4]
Where the second column represents the time, and will change, changing the problem. I would like to split this matrix so that creating a row vector for the time, in this way changing the vector, the matrix A will change automatically. It is possible? Thank you

MATLAB numeric variables(including matrices, arrays, etc. of the built-in data types) are value objects. when you copy a to the variable b, both variables are independent of each other. Changing the value of a does not change the value of b.
So It is not possible to change matrix A automatically.You have to change A matrix whenever a change in row vector for time.
A = [A(:,1),b'] %b is the row vector for time
