I=[10 20 30 30 40 50 60 70 80 90 100];
V=[1.5 1.9 2.2 2.5 2.77 3 3.25 3.5 3.72 3.95 4]; % this vector has less number of elements
V has only 10 elements
i=0;
j=0;
for M=0.2:0.05:0.8
j=j+1; % change it to 1 and try

It is because I has 11 elements and V has only 10 elements. Thy should have the same number of elements to plot them as (x,y) pairs.
