First find the [workspace] window, as shown in the figure.

Right-click the blank space of [workspace], click [new] to create a new variable, as shown in the figure, named mat2

Double-click mat2, and the corresponding window will appear. In the mat2 window, you can enter the matrix elements according to the original shape of the matrix.
