One option is on the C++ side is to allocate the 2D array of floats as 1D and assigned to the first pointer of pointers, then fill in the remainder pointers in the array of pointers with the proper offset. And on the Fortran side you can now create the 2D array descriptor. WebApr 10, 2024 · Dynamic arrays consist of a length and a pointer to the array data. Multiple dynamic arrays can share all or parts of the array data. Best Practices: Use dynamic arrays instead of pointer arrays as much as practical.
