stress = Ck45(:,1); strain = Ck45(:,2); plot(strain,stress); I am plotting a stress strain curve but the curve is not starting from zero so my professor told me to shift he curve but for that I must subtract the 1st-1st element 2nd -1st element so on

stress = Ck45(:,1); strain = Ck45(:,2); plot(strain,stress);the curve for this is not starting from zero and I need to shift it to zero .how can i write a code where I can subtract 1st element from 1st and than second from first and so on.. of the same matrices to create a new set of matrices.

To shift a array to zero, you can substract the array with minimum value of the array.

strain = strain- min(strain);

If you want to substract successive elements you can use either diff or gradient
