The MatrixMultiply(x,y,opts) command computes the matrix multiplication product of two Tensor objects.

$\mathrm{with}\left(\mathrm{DeepLearning}\right)\:$

$\mathrm{m1}≔\mathrm{Constant}\left(⟨⟨-92.1\,-31.3\,67.3⟩|⟨-35.0\,65.0\,41.0⟩⟩\right)$

$\mathrm{m1}≔\left[\begin{array}{c}\mathrm{DeepLearning\; Tensor}\\ \mathrm{Shape:\; [3,\; 2]}\\ \mathrm{Data\; Type:\; float[8]}\end{array}\right]$

$\mathrm{m2}≔\mathrm{Constant}\left(⟨⟨99.7\,29.0⟩\left|⟨44.5\,-14.0⟩\right|⟨45.0\,24.0⟩⟩\right)$

$\mathrm{m2}≔\left[\begin{array}{c}\mathrm{DeepLearning\; Tensor}\\ \mathrm{Shape:\; [2,\; 3]}\\ \mathrm{Data\; Type:\; float[8]}\end{array}\right]$

$\mathrm{MatrixMultiply}\left(\mathrm{m1}\,\mathrm{m2}\right)$

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

The DeepLearning/Tensor/MatrixMultiply command was introduced in Maple 2019.
