Description
|
|
•
|
The Lcoeff(A,x) command computes the leading coefficient of a matrix of polynomials A.
|
•
|
The Lcoeff[row](A,x) command computes the leading row coefficient of A. That is, it computes a matrix with rows that are the leading coefficient of each row of A.
|
•
|
The Lcoeff[column](A,x) command computes the leading column coefficient of A.
|
•
|
The Tcoeff(A,x), Tcoeff[row](A,x), and Tcoeff[column](A,x) commands compute the trailing coefficient, trailing row coefficient, and trailing column coefficients of A, respectively.
