How can I get the Y value at once?

function Y = objectivefunction (X)

x1 = ;
x2 = ;
x3 = ;
x4 = ;
   

Y = x1*x4*[x1+x2+x3]+x3;

end

There are 20 x1, x2, x3 and x4 respectively.

I want to get 20 Y value.

I want to import data through Excel or Table.

Please let me know. Thank you.

Did you try this:

t = readtable('x1x2x3x4.xlsx')
x1 = t.x1;
x2 = t.x2;
x3 = t.x3;
x4 = t.x4;
Y = x1 .* x4 .* (x1 + x2 + x3) + x3;
