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.

Webrcond is a more efficient but less reliable method of estimating the condition of a matrix compared to the condition number, cond. Extended Capabilities C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. GPU Code Generation Generate CUDA® code for NVIDIA® GPUs using GPU Coder™. Thread-Based Environment WebRCOND = 1.306145e-17. x = 4×1 1.5000 2.5000 -0.5000 0.5000 When rcond is between 0 and eps, MATLAB® issues a nearly singular warning, but proceeds with the calculation. When working with ill-conditioned matrices, an unreliable solution can result even though the residual (b-A*x) is relatively small.
