Create system of equations from Matrix

Is there a way to create a system of nonlinear equations to be solved in Matlab gotten from n-dimensional matrix which is created on some way?
For example, user has decided that n should be 4 and the generated matrix taken from the output - Command Window (there is a special code to produce this matrix) is
Matrix1 =
1 1 1 1
1 1 0 1
1 0 1 0
1 1 0 1
Now I need to create (automatically) system of equations like this (based on matrix1) and solve it in Matlab:
(1-x1)*(1-x2)*(1-x3)*(1-x4)=0
(1-x1)*(1-x2)*(1-x4)=0
(1-x1)*(1-x3)=0
(1-x1)*(1-x2)*(1-x4)=0

Why do you want to generate the system ? It has the obvious solution x(i) = 1 for all i.

Yes, it is possible to create a system of nonlinear equations based on the given matrix in MATLAB. You can use the symbolic math toolbox in MATLAB to define the variables and equations symbolically. Here's how you can do it:
% Define the variables symbolically
syms x1 x2 x3 x4
% Define the equations based on the given matrix
eq1 = (1-x1)*(1-x2)*(1-x3)*(1-x4) == 0;
eq2 = (1-x1)*(1-x2)*(1-x4) == 0;
eq3 = (1-x1)*(1-x3) == 0;
eq4 = (1-x1)*(1-x2)*(1-x4) == 0;
solutions = solve([eq1, eq2, eq3, eq4], [x1, x2, x3, x4]);
disp(solutions)
Running this code will provide you with the solutions to the system of equations.
Thank You!
