Thanks for the amazing software (uqlab). I was trying to implement a system reliability problem of three components in Parallel using uqlab but get below error message.
Error using mvncdf (line 193)
SIGMA must be a square, symmetric, positive definite matrix.
Error in Systemrel (line 40)
Pf_FORM = mvncdf(-B, [0; 0; 0], R);
I have attached the MATLAB code and will greatly appreciate any help and advice on this .
