I have thw following problem
Considering the matrix
M = [1 2 3; 4 5 6; 7 8 10]
And the vector
E = [Ex; Ey; Ez]
And
B = [1; 4; 10]
Does anyone knows how to find the values of E components in matlab, considering
M*E=B?

Use the following command, using mldivide or the equivalent operator \:
E = M\B
This results in:
E =
4.0000
-6.0000
3.0000
Verification:
M*E
ans =
1.0000
4.0000
10.0000

I understood your thoughts but shouldn't it be: E = B\M? – Mac Dec 15 '14 at 12:52

1Nope, please check the description and syntax of `mldivide` provided by the mathworks. It solves the equation `Ax = B` for x, using `x = A\B` – Nick Dec 15 '14 at 13:01

Furthermore, it doesn't hurt to accept a correct answer... :) – Nick Dec 15 '14 at 13:09

DO you know how can I do the same thing in Python? – Mac Feb 04 '15 at 19:38

1Sorry @Mac, I don't know anything about Python... Well I know that it's a snake :) – Nick Feb 06 '15 at 09:24
