vDSP_vgenpD
Generates the double-precision linearly interpolated values of a vector at the specified indices.
Declaration
extern void vDSP_vgenpD(const double *__A, vDSP_Stride __IA, const double *__B, vDSP_Stride __IB, double *__C, vDSP_Stride __IC, vDSP_Length __N, vDSP_Length __M);Parameters
- __A:
The input vector that defines the values that the function interpolates.
- __IA:
The distance between the elements in the values vector.
- __B:
The input vector that defines the indices at which the function interpolates.
- __IB:
The distance between the elements in the indices vector.
- __C:
The output vector.
- __IC:
The distance between the elements in the output vector.
- __N:
The number of elements that the function processes.
- __M:
The number of elements in the values and indices input vectors.

Discussion
The following code creates a five-element vector from two values using linear interpolation. The last index in indices determines the length of the operation result:
