ten_reshape_back

Performing reversed tensor reshape on a given tensor.

To test if a tensor time series following a Tucker-decomposition factor model has a Kronecker product structure. Supplementary functions for tensor reshape and its reversal are also included.

ten_reshape_back function

<dl><dt>ten</dt>
<dd>An array representing a tensor.</dd>
<dt>AA</dt>
<dd>A vector representing mode indices to reshape along back.</dd>
<dt>original.dim</dt>
<dd>A vector representing the dimension of the original tensor before reshape.</dd>
<dt>time.mode</dt>
<dd>Logical. TRUE if mode-1 of the input tensor is the time mode and hence not involved in reshape; otherwise reshape is on the entire input tensor. Default is TRUE.</dd></dl>
