Parameters
- pRandUniState
- Pointer to the structure containing parameters for the generator of noise.
- low
- Lower bound of the uniform distribution range.
- high
- Upper bound of the uniform distribution range.
- seed
- Seed value used by the pseudo-random number generation algorithm.
Description
This function initializes the pseudo-random generator state structure
pRandUniState
in the external buffer. The uniform distribution range is specified by the lower and upper bounds low
and high
, respectively. Before using this function, you need to compute the size of the external buffer by using the ippsRandUniformGetSize
function.The example of using this function is similar to the example provided with the Histogram function description.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepRandUniStatepointer isNULL.
- ippStsMemAllocErr
- Indicates an error when there is not enough memory for the operation.
