i have homework about least square solution that i have a linear system of equation
x1 + x2 + x3 = 4
-2x1 + 2x2 + x3 = 6
x1 + x2 - 2x3 = 6
anyone know how to find least square solution of the least square solution in matlab?
(answer output must be in vector form(x1,x2,x3))

Although you should do your homework yourself I think I can help you : )
This problem could be solved with the backslash operator (or mldivide)
X = [1 1 1
-2 2 1
1 1 -2]; % These are the coefficients from your linear system
Y = [4
6
6]; % these are the responses from your linear system
P = X\Y; % and P' would be your [x1,x2,x3]
