mols catches some stupidity of the programmer but I have managed to get segfaults in some situations when I count the dimensions wrong. An example matrix y = {1; 2; 1} matrix x = {1; 1; 1} matrix errorpar = {1; 1} mols(y, x * errorpar) #ok mols(y, x + errorpar) #ok mols(y, x * errorpar + errorpar) #segfault If it possible would be nice if the latter could also be caught.
