makeMatrix(randRange(0, 9, DIM_1, DIM_2)) matrixTranspose(MAT) matrixPad(SOLN_MAT, 3, 3) "\\textbf " + randFromArray("ABCDEF") printSimpleMatrix(SOLN_MAT)

PRETTY_MAT_ID = printSimpleMatrix(MAT)

What is PRETTY_MAT_ID^{T}?

To find the transpose, swap the rows and columns.

PRETTY_MAT_ID^{T} = PRETTY_SOLN_MAT
