WebMar 25, 2024 · Matlab believes it is singular due to limits on floating point precision. Documentation dictates that using det (x) to determine if a matrix is singular is poor practice, and using rcond (x) (for instance) is better [2]. However, in this case, det (x) yields the analytical solution of the determinant.
