Pointer to an array containing the output vector y. |
The v?MaxMag function returns a vector with element values equal to the element with the larger magnitude from each pair of corresponding elements of the two vectors a and b:
If |ai| > |bi| v?MaxMag returns ai, otherwise v?MaxMag returns ai.
If |bi| > |ai| v?MaxMag returns bi, otherwise v?MaxMag returns ai.
Otherwise v?MaxMag behaves like v?Fmax.

|---|---|---|---|---|
| ai not NAN | NAN | ai | ||
| NAN | bi not NAN | bi | ||
| NAN | NAN | NAN |
