I have a matrix 6x1000 double in matlab.How can i convert it to 3D as 6x1000x1 format ?

My input is times series data and i need to give it to sequence input layer for performing convolution.

I have tried

B=reshape(X,6,1000,1);

It didnt give errors, but B appeared same as 6 x 1000 double.

Input size of sequence input layer is given as 6 x 1000 x1.

and without reshaping/converting i am getting the below error while executing.

Invalid training data. Sequence responses must have the same sequence length as the

corresponding predictors.

They are already exactly the same arrays:

"Arrays in MATLAB are N-dimensional, with an infinite number of trailing singleton dimensions."

The infinite trailing singleton dimensions might not be displayed, but implicitly they are always there. See also:

The error message spoke of two things: response and predictor. You only mention one size.
