My array is [2.5 2.6 ........ 4.2]

I want to it to be displayed where 2.5 becomes 0% and 4.2 becomes 100%

you would take your array, subtract the minimum, then divide by the resulting maximum x 100

x = [2.4:.4:4.2];
x  = x-min(x);
disp(x)

         0    0.4000    0.8000    1.2000    1.6000

percX = x./(max(x(:)))*100

percX = 1×5

0 25.0000 50.0000 75.0000 100.0000
