julia_array is a helper function to create Julia arrays including vectors, matrices and etc.
And it can be used in functions to facilitate automatic differentiation.
julia_array(data, n1, n2, ...)
| data | the data to create the array. |
|---|---|
| n1, n2, ... | the dimensions. |
If n1 is missing, then all the dimensions will be ignored, and the result will be a Julia array coresponding to the data argument. If n1, n2, ... are given, they will determine the shape of the result, and data will be used for the content.
