The m-file imsl2c.m (IMSL to 'C') automates the process of writing the source code for C MEX files which, in turn, call routines in the IMSL numeric libraries. These libraries are included in the professional version of DEC's Digital Visual Fortran. The mat-file imsl.mat contains structures that have the types, names, and parameters needed by imsl2c.m to create function prototypes and correct calling conventions for routines in the IMSL libraries.

Once the C file has been created, the m-file imslmex is used to create the mex with the aforementioned C-file and links against the double precision versions of the IMSL libraries.

There are some routines that use a pointer to another function, e.g. routines for solving ODE's, optimization problems, etc. After using imsl2c.m for these routines, it is up to the user to edit the resulting C-file and put in the function body for the 'pointed to' function. A prototype for this function will automatically be created named 'FCN'.

Additional input/output arguments can be created by imsl2c, but it is up to the user to edit the c-file such that these variables are defined, assigned values, etc.

Tested with Matlab ver 5.2.1.1420 on WIN95.
