MTM[collect] - collect coefficients

Calling Sequence

collect(A, v)

Parameters

A

-

polynomial, Array of polynomials

v

-

(optional) expression

Description

• 

For polynomial A, the function collect(A,v) will return a polynomial equal to A, but with coefficients of like powers of v collected.  

• 

If the parameter v is omitted, then v is taken to be the default symbol given by findsym(A,1).

• 

If A is an array, then collect(A,v) will return an array M with the same dimensions of A. For each element a of A, the corresponding element in M will have the value collect(a,v).
