Sometimes it is a good idea to think before attempting to write a zmatrix. For historical reasons gaussian has been around for more than 25 years, and new versions try to be partly compatible with older ones, so the input format has not changed much, the order of the different items in the file has to be followed very rigorously, because. Graphical interface for gaussian 09 sketch molecules setup gaussian 09 input files graphically examine results molden.

This can also happen in a link job if a previous step uses default coordinates which wipes the z matrix and then you try to modify the z matrix with geommodify. The best way to reformat the z matrices depends on what additional programs you want to interface subsequently, i presume. For new program features, like gaussian 03 support, please consult the.

We have seen how to write a system of equations with an augmented matrix and then how to use row operations and backsubstitution to obtain rowechelon form. I am assuming that you want to create a matrix of random numbers with a gaussian distribution and then multiply each element in your original matrix with this random number matrix in an elementwise fashion.
