Hi!
I am new to matlab and have this problem:
[ -1 0 0 ]*V == [ 0 -1/3 0 ] + [ -4 4 0 ]*W
How do I code this to find V and W?

Read about solve() and vpasolve()
syms V W
[V,W]=solve([ -1 0 0 ]*V == [ 0 -1/3 0 ] + [ -4 4 0 ]*W,V,W)
Command window:

V =
1/3
W =
1/12

syms V W
VW = solve([ -1 0 0 ]*V == [ 0 -1/3 0 ] + [ -4 4 0 ]*W)
VW =
struct with fields:
V: [1×1 sym]
W: [1×1 sym]
>> VW.V
ans =
1/3
>> VW.W
ans =
1/12
