I have a function that takes a vector as an input. I want to run this function multiple times with a for loop while varying this vector from [0 100] to [100 0]. How can I vary this vector like that? Thank you.

Consider moving a point from [0, 100] to [100, 0] on a plane. How do you move it? You have to specify other conditions. For examples, you can mover the point uniformly along an arc on a circle, or a straight line between the 2 points.

Specfify your requirements first.

It would be a straight line.

Maybe something like this?

npoints = 11;
v = linspace(0,100,npoints);
for p = 1:npoints
    thisv = [v(p) v(npoints-(p-1))];
    myfunction(thisv);
end

p1 = [0 100]; p2 = [100, 0];
dp = (p2-p1)/100;
di = 10;  % di=1
for i=0:di:100
    p = p1 + i*dp;
    fprintf('%3d  %3d\n', p)
