Hello.

I am trying to extract all the coefficients of a linear equation by calling coeffs function.

> 

eq := 1.2*a[2]+1.3*a[3]+1.1*a[1]+1.0

1.2*a[2]+1.3*a[3]+1.1*a[1]+1.0

 (1)
> 

 
> 

vars := [seq(a[i], i = 1 .. 3)]

[a[1], a[2], a[3]]

 (2)
> 

coeffs(eq, vars)

1.0, 1.2, 1.3, 1.1

 (3)

I expected I receive the coefficients in the same order as in vars variable, but I was wrong. How to extract coefficients in the order I need?
