用于训练的多维时间序列结构 Multidimensional time series structure for training.

If I intend to format training data as 4 (H height) * 6 (W width) * 128 (T time), and there are a total of 1000 training cases, what should the format of the input data be like? Should it be a 1000x1 cell, where each cell contains a 4x6x128 double? Each of my time slices is a 4x6 matrix. I've seen many online sources mentioning the need to set a 'channel' dimension; how should this be handled?

THX！
