Matlab and Fortran and ODE

1,509 Views

Hello

At my faculty department of chemical engineering they switched from fortran to matlab some years ago. Matlab is easier but it does not have the beauty of fortran. I will never change to code in fortran. Recently I had to solve some ordinary differential equations (ODE) and I made a quick search to find the new methods. I found that Matlab implements a new method based on NDF's (numerical differentiation formulas) instead of the BDF (gear method). I saw a comparison between the two methods and it seems that Matlab method is more accurate. I tried to find a fortran suite that implements ODE based in NDF's methods and I couldn't find any. Does any anyone knows about a fortran code based on this method?

thanks in advance

Peter
