Matrix
Transpose
Transposes matrix. For a complex matrix, TRN nds the conjugate transpose.
TRN(matrix)
Example:
TRN returns
Determinant
Determinant of a square matrix.
DET(matrix)
Example:
DET returns -2
RREF
Reduced Row-Echelon Form. Changes a rectangular matrix to its reduced row-echelon form.
RREF(matrix)
Example:
RREF returns
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.
