MATLAB: Vector equation with two unknowns

2 unknown vector equationvector equation

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?

Best Answer

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

You need to convert the symbolic values to double for all the cases:

a1=double(vpasolve(eqn1,a1,[1/4 1/3]));
