The interfaces of the Data Fitting functions are in lowercase, while the names of the types and constants are in uppercase.
The names of all routines have the following structure:
df is a prefix indicating that the routine belongs to the Data Fitting component of Intel MKL.
[datatype] field specifies the type of the input and/or output data and can be s (for the single precision real type), d (for the double precision real type), or i (for the integer type). This field is omitted in the names of the routines that are not data type dependent.
<base_name> field specifies the functionality the routine performs. For example, this field can be newtask1d, interpolate1d, or deletetask
