typedef struct _clprobdistExponential clprobdistExponential |
Exponential distribution object [device].
A structure that represents an exponential distribution object.
clprobdistExponential* clprobdistExponentialCreate | ( | cl_double | lambda, |
size_t * | bufSize, | ||
clprobdistStatus * | err | ||

Create a distribution object.
Create a new exponential distribution object. Since this function allocates memory for the new distribution object; clprobdistDestroy() must be called to release the allocated memory.
