  *
  * This function computes the new data format after transposing a tensor.
  *
+ * It follows these steps:
+ *   1. Retrieves the permutation mapping from the input format.
+ *   2. Applies the given output dimensions order to compute the new permutation.
+ *   3. Identifies the corresponding data format after applying the new permutation.
+ * 
  * @param inputDataFormat The data format of the input tensor.
  * @param outputDimsOrder The permutation applied to the input tensor's dimensions.
  * @return DataFormat The computed output data format after applying the permutation.
