How can I find the coefficients of the symbolic variables in a linear equation?

Hi guys,

I want to draw out the coefficients of the symbolic variables in a linear equation, like:

syms x1 x2 x3

0*x1+5*x2+0*x3-10=0

and the coefficients are [0,5,0].

I used the "*coeffs*" fuction in the toolbox, but it omits the "zero coefficients.

please help me out. thanks in advance.

Maybe the thread Isolate Coefficients of Multivariate Linear Polynomial can help you.
