collect

Collect coefficients

Syntax

• R = collect(S)
  R = collect(S,v)
  

Description

For each polynomial in the array S of polynomials, collect(S) collects terms containing the variable v (or x, if v is not specified). The result is an array containing the collected polynomials.

Examples

The following statements

• syms x y;
  R1 = collect((exp(x)+x)*(x+2))
  R2 = collect((x+y)*(x^2+y^2+1), y)
  R3 = collect([(x+1)*(y+1),x+y])
  

return

• R1 = 
  x^2+(exp(x)+2)*x+2*exp(x)
  
  R2 = 
  y^3+x*y^2+(x^2+1)*y+x*(x^2+1)
  
  R3 = 
  [(y+1)*x+y+1, x+y]
