There is an error with your graph parameters for

**group_celerity_k**with options k=0:4 depth=1:10:4**Error Message:**Function group_celerity_k failed. Ensure that: **Invalid C++**

### Example 1

#include <stdio.h> #include <codecogs/engineering/waves/group_celerity.h> using namespace Engineering::Waves; int main() { printf(" k Cg "); for(double k=0.01; k<1;k+=0.1) { printf("\n %.6lf", k); double w=group_celerity_k(k,2); printf(" %.3lf", w); } }

**Output:**`k Cg ??`

### Parameters

k wave-number defines as (). [rad/m] depth the depth of the water to mean sea level. A value of zero or less corresponds to deep water. [m] gravity acceleration due to gravity (default 9.8066 m/s ^{2}). [m/s^{2}]

### Returns

- wave-frequency (). [rad/s]
