double rc_vector_norm(rc_vector_t v, double p)¶
Returns the vector norm defined by sum(abs(v)^p)^(1/p), where p is any positive real value.
Just like the matlab norm(v,p) function.
Most common norms are the 1 norm which gives the sum of absolute values of the vector and the 2-norm which is the square root of sum of squares. for infinity and -infinity norms see rc_vector_max and rc_vector_min
- Parameters
v – [in] User’s vector struct
p – [in] Which norm to use. Positive real values only.
- Returns
vector norm. Prints error message and returns -1.0f on error.
