flatten

flatten(matrix: any[] | Mat | Tensor) : any[]

param matrix - an Array, Mat or Tensor

returns: any[] - A list with all elements from matrix. The order of elements follows the dimensions or shape order.

This function is a useful tool for taking a multidimensional matrix, for example a 2-D matrix, and "flattening" it into a 1d Array i.e. a list. Here is an example:
