Replaceability

The external interfaces provided by KML_BLAS are the same as those provided by MKL-BLAS in terms of interface parameters and function names, and can be directly used to replace the library.

Table 1, Table 2, Table 3, Table 4 show the mapping between alternative interfaces and MKL interfaces.
