Try this:
disp(' ')
disp('This program computes the vectors v that are:');
disp(' - ortogonal to w')
disp(' - have length 1')
disp(' - have zero as the first component')
disp(' ')
str = input('Please enter a vector w=[w1 w2 w3]: ', 's');
w = sscanf(str, '%f %f %f')
disp(' ');
v1=1*w;
v2=2*w;
v3=3*w;
v4=4*w;

You can directly use the elements of a vector through indexing. You don't need to extract them into separate variables.
w = [1 4 9] % Sample
v = w(3) - w(2).^2 + w(1) % 9 - 4*4 + 1 = -6
