FORTRAN does not have such a system apart from for functions that return a single output. In MATLAB code, the function declaration has two separate lists for variables, inputs on the right and outputs on the left. During the conversion, a simple find and replace can be used to replace these lines. The first word is the variable name, which may be followed by extra text for a comment. This can be followed by an integer representing the number of array dimensions. The next character denotes the type ( i for integer, f for float/double or s for string). In our system (shown below), the variable declarations are identified by a comment beginning with a #.

This method was much faster, because the code author already knows the type and purpose of each variable. A solution used during our project required collaboration from the author of the MatLab code, whereby declarative comments were added to the top of every MatLab function. Using MATLAB itвЂ™s possible to see all variables that are in scope and their contents, but using this as the primary source of variable definitions is time consuming. A major challenge of converting dynamically and statically typed languages is working out what variables need to be declared. In FORTRAN, variables must be declared before use.

The most noticeable difference between the two languages is that MATLAB is dynamically typed, while all variables in FORTRAN are declared at the top of the scope. This article describes how we solved those problems. Recently, OCC completed a project converting MATLAB code to FORTRAN 95 which presented us with some interesting problems due to their differences in the treatment of variables, functions and matrices.
