solve an underdetermined set of equations with minimum norm from guess in matlab

To solve an underdetermined system of linear equations Ax = b with minimum norm, you can use the pseudo-inverse to find the solution. The minimum norm solution for an underdetermined system is x = A^T(AA^T)^{-1}b.

Here's the code snippet in MATLAB:

main.m
A = ... % specify the matrix A
b = ... % specify the vector b
x_guess = ... % provide the initial guess for x

x_min_norm = A' * inv(A * A') * b;

% Print the minimum norm solution
disp(x_min_norm);

Make sure to replace A, b, and x_guess with your specific matrix and vector values.
