MATLAB: Evaluate Function at different data points from vectors

evaluate function

I have three vectors
x = [ 0.05 0.06 ]
y = [ 1.23 1.41 ]
z = [ 0.1 0.2]
Now I want to evaluate function at all values such as
f(0.05,1.23,0.1)=2.6629
f(0.05,1.23,0.2)=2.7629
f(0.05,1.41,0.1)=3.1381
f(0.05,1.41,0.2)=3.2381
f(0.06,1.23,0.1)=2.6729
f(0.06,1.23,0.2)=2.7729
f(0.06,1.41,0.1)=3.1481
f(0.06,1.41,0.2)=3.2481
These values should be saved in a vector.

Use meshgrid to generate all combinations and make your function accept vector entries. Ex: 
f = @(x,y,z)x.*y+z; % Insert your function
x  = [ 0.05 0.06 ];
y =  [ 1.23 1.41 ];
z = [ 0.1 0.2];
[XX,YY,ZZ] = meshgrid(x,y,z); % Create all possible combinations
w = f(XX(1:end),YY(1:end),ZZ(1:end))
w =
    0.1615    0.1705    0.1738    0.1846    0.2615    0.2705    0.2738    0.2846
