datatype = one of integer[4],integer[8],float[4],float[8],complex[4], or complex[8]

The value of option datatype specifies the type of data this Tensor will hold. By default, the datatype is float[4].

name = string

The value of option name specifies an optional name for this Tensor, to be displayed in output and when visualizing the dataflow graph.

The IdentityMatrix(c) command creates a Tensor in the active dataflow graph whose value is the m by n identity matrix.

This function is part of the DeepLearning package, so it can be used in the short form IdentityMatrix(..) only after executing the command with(DeepLearning). However, it can always be accessed through the long form of the command by using DeepLearning[IdentityMatrix](..).

The implementation of EinsteinSummation uses the tf.eye command from the TensorFlow Python API. Consult the TensorFlow Python API documentation for tf.eye for more information.

$\mathrm{id}≔\mathrm{IdentityMatrix}\left(4\,3\,\mathrm{datatype}=\mathrm{float}\left[8\right]\right)$

$\mathrm{id}≔\left[\begin{array}{c}\mathrm{DeepLearning\; Tensor}\\ \mathrm{Shape:\; [4,\; 3]}\\ \mathrm{Data\; Type:\; float[8]}\end{array}\right]$

$\left[4\,3\right]$

The DeepLearning[IdentityMatrix] command was introduced in Maple 2018.
