MATLAB: How to define and assign a variable

datadata acquisitiondata importdatabasevariablevariables

I have n no of variable starting with 'VAR' and VAR1 = [2 5 4 8 9 3 6 4 1 0 3 5], VAR2 = [4 7 4 0 9 3 3 4 1 2 7 5], VAR3 = [2 5 3 8 9 6 6 4 8 0 1 5] and so on. How can i define the variable by one command where i want to use i (i = 1,2,3,4,…..) and then assign the respective value in corresponding variable?

  • If you want to put them all in a matrix (good programming practise), use a loop and eval:
    VAR1 = [2 5 4 8 9 3 6 4 1 0 3 5];
    VAR2 = [4 7 4 0 9 3 3 4 1 2 7 5];
    VAR3 = [2 5 3 8 9 6 6 4 8 0 1 5];
    NrVAR = 3;
    for k1 = 1:NrVAR
    VARmat(k1,:) = eval(sprintf('VAR%d',k1));
    end
