The argument
matrix
can refer to either a vector or a
matrix.
Matrix functions
The matrix functions are available in the Matrix category
on the Math menu:

Transpose
Transposes
matrix
. For a complex matrix, TRN finds the
conjugate transpose.
TRN

Determinant
Determinant of a square
matrix
.
DET
(

RREF
Reduced Row-Echelon Form. Changes a rectangular
matrix
to its reduced row-echelon form.

Create
Make
Creates a matrix of dimension
rows
×
columns
, using
expression
to calculate each element. If
expression
contains the variables I and J, then the calculation for each
element substitutes the current row number for I and the
current column number for J. You can also create a vector
by the number of elements (e) instead of the number of
rows and columns.

Examples
MAKEMAT(0,3,3)
returns a 3 × 3 zero matrix,
[[0,0,0],[0,0,0],[0,0,0]]
.
MAKEMAT(

.
MAKEMAT(I+J–1,2,3)
returns the 2 × 3 matrix
[[1,2,3],[2,3,4]]
Note in the example above that each element is the
sum of the row number and column number minus 1.
