randRange(1, 4)        randRange(1, 4)        makeMatrix(randRange(-2, 4, DIM_1, DIM_2))        "\\textbf " + randFromArray("ABCDEF")                    printSimpleMatrix(MAT_A)

PRETTY_MAT_ID = PRETTY_MAT_A

What are the dimensions of matrix PRETTY_MAT_ID?

DIM_1                \times                DIM_2

The first dimension is the number of rows in the matrix. How many rows does PRETTY_MAT_ID have?

DIM_1

The second dimension is the number of columns in the matrix. How many columns does PRETTY_MAT_ID have?

DIM_2

So, PRETTY_MAT_ID is a DIM_1 \times DIM_2 matrix.
