matrix/DemoLeastSquares01

Demonstrate least squares method to find a regression line through noisy points Line drawn in red is the estimated line, in green is the ground-truth line

Ax = b => x = A⁻¹b because A is likely inconsistent, we look for an approximate x based on AᵀA, which is consistent. x̂ = (AᵀA)⁻¹ Aᵀb
