Name
LQ Returns the LQ factorization of an m × n matrix.
LR Uses currently selected statistical model to calculate the
linear regression coefficients (intercept and slope).
LSQ Returns the minimum norm least squares solution to any
system of linear equations where A × X = B.
LU Returns the LU decomposition of a square matrix.
LVAR Returns a list of variables in an algebraic object.
MAD Returns details of a square matrix.
MAIN Displays a menu of CAS categories.
MANT Returns the mantissa of the argument.*
MAP Applies a specified program to a list of objects or values.
↑MATCH
Rewrites an expression that matches a specified pattern.
↓MATCH Like ↑MATCH, but works top-down not bottom-up.
MATR Displays a menu of matrix commands.
MAX Returns the greater of two inputs.*
