I have multiple vectors and numbers in all of them lie between 0 and 1, I want to do 'normalize' the data such that the maximum point in each vector now definitely touches 1 and minimum point definitely touches 0 and numbers in between gets manipulated accordingly.
How can I do this?

Any number of ways; a couple...
z=interp1([min(x) max(x)],[0 1],x);
b=polyfit([min(x) max(x)],[0 1],1);
z=polyval(x);
