@interface BCFortranArray : NSObject

/* utility classes for managing 1 or 2 dimensional double/integer arrays
 
  data stored in malloc'd unsigned char *buffer, with 2D array stored like pixels in an image (i.e. y sequential rows of x size each)
 
 For compatiblity with ported FORTRAN code, array elements are accessed using 1-indexing (not 0-indexing)
 e.g. [NSFortranArray valueAtX:1] returns buffer[0]
 e.g. [NSFortranArray valueAtX:max_x] returns buffer[max_x-1]
