Method Description
Dispose ( ) : void

Dispose
GetTensor4dDescriptor ( cudnnDataType &dataType, int &n, int &c, int &h, int &w, int &nStride, int &cStride, int &hStride, int &wStride ) : void

This function queries the parameters of the previouly initialized Tensor4D descriptor object.
GetTensorNdDescriptor ( int nbDimsRequested, cudnnDataType &dataType, int &nbDims, int dimA, int strideA ) : void

This function retrieves values stored in a previously initialized Tensor descriptor object.
SetTensor4dDescriptor ( cudnnTensorFormat format, cudnnDataType dataType, int n, int c, int h, int w ) : void

This function initializes a previously created generic Tensor descriptor object into a 4D tensor. The strides of the four dimensions are inferred from the format parameter and set in such a way that the data is contiguous in memory with no padding between dimensions.
SetTensor4dDescriptorEx ( cudnnDataType dataType, int n, int c, int h, int w, int nStride, int cStride, int hStride, int wStride ) : void

This function initializes a previously created generic Tensor descriptor object into a 4D tensor, similarly to cudnnSetTensor4dDescriptor but with the strides explicitly passed as parameters. This can be used to lay out the 4D tensor in any order or simply to define gaps between dimensions.
SetTensorNdDescriptor ( cudnnDataType dataType, int nbDims, int dimA, int strideA ) : void

This function initializes a previously created generic Tensor descriptor object.
