how can i save my values of u into a vector, so i have the result of all the u-values.

for x=(0:0.1:1)
z=ones(1,11);
L=3.5;
v = [0.091, -0.061, 0.518, -0.07]';
N1 = 1 - 3*(x/L).^2 + 2*(x/L).^3;
N2 = x.*(1 - x/L).^2;
N3 = 3*(x/L).^2 - 2*(x/L).^3;
N4 = (x/L - 1).*x.^2/L;
u = N1*v(1) + N2*v(2) + N3*v(3) + N4*v(4)
end

The loop is not necessary. Just use matrix multiplication.
One approach —
x=(0:0.1:1).'; % Column Vector (Creates The 'N' Values As Column Vectors)
L=3.5;
v = [0.091, -0.061, 0.518, -0.07]';
N1 = 1 - 3*(x/L).^2 + 2*(x/L).^3;
N2 = x.*(1 - x/L).^2;
N3 = 3*(x/L).^2 - 2*(x/L).^3;
N4 = (x/L - 1).*x.^2/L;
u = [N1 N2 N3 N4] * v % Matrix Multiplication
u = 11×1
0.0910 0.0865 0.0849 0.0862 0.0901 0.0965 0.1052 0.1159 0.1286 0.1429
