Chapter 10: Matrices 152

Negation

Negating a matrix returns a matrix in which the sign of every element is changed.

matrix

abs(

abs( (absolute value, MATH NUM menu) returns a matrix containing the absolute value of each

element of

matrix.

abs(matrix)

round(

round( (MATH NUM menu) returns a matrix. It rounds every element in matrix to #decimals ( 9). If

#decimals is omitted, the elements are rounded to 10 digits.

round(matrix[,#decimals])

Inverse

Use the

function (œ) or › L1 to invert a matrix. matrice must be square. The determinant cannot

equal zero.
