As a simple but not trivial program using multidimensional arrays, please see this example > [@Performance of vectorized code in ifort and ifx](https://fortran-lang.discourse.group/t/performance-of-vectorized-code-in-ifort-and-ifx/7783): > > I created a small Fortran example of discrete dynamic programming that occurs quite often in macroeconomics. It is an optimal savings problem for a consumer who received idiosyncratic shocks to their income. I was interested in comparing loop-based Fortran code vs vectorized code, both in ifort and in ifx. Just to avoid misunderstandings, the definition of “vectorizing” that I am using is the following: I vectorize if I replace this code do i=1,n yvec(i) = exp(xvec(i)) enddo with the followin… I created the program above for a post on this forum a while ago (you can find the link to github repo in the post) I might have another example that uses 4-dimensional arrays, if I can dig it out --- _[View the full topic](https://fortran-lang.discourse.group/t/scientists-are-using-artificial-intelligence-and-large-language-models-to-rewrite-old-code-in-modern-languages/9598)._
