// The node creation interface for the "app.userkernels.tensor_cos" kernel.
// This user kernel example expects parameters in the following order:
// parameter #0 -- input tensor of format VX_TYPE_INT16
// parameter #1 -- output tensor of format VX_TYPE_INT16
//
// TODO STEP 01:********
// 1. Use vxGetKernelByEnum API to get a kernel object from USER_KERNEL_TENSOR_COS.
// Note that you need to use vxGetContext API to get the context from a graph object.
// 2. Use vxCreateGenericNode API to create a node from the kernel object.
// 3. Use vxSetParameterByIndex API to set node arguments.
// 4. Release the kernel object that are not needed any more.
// 5. Use ERROR_CHECK_OBJECT and ERROR_CHECK_STATUS macros for error detection.
