Augment
Creates a matrix from several matrices. The Rows and Columns properties decide how many input matrices there are and where in the resulting augmented matrix these matrices will appear.
For instance if the Rows and Columns properties are set to 2, 4 input matrices are created. The first input matrix will be placed in the upper left corner of the resulting matrix, the second in the upper right corner, the third in the lower left corner, and the fourth in the lower right corner.
If the input matrices do not match in terms of rows and columns with the matrices on the same row or column, zeros are inserted.
