Matlab question NEED FOR HELPPP!!

Question

Write a MATLAB function to solve the system of linear equations given below using matrix division. Make r an input to the function and x will be the output.

⌈ 5 2r r ⌉ { x₁ } { 2}

| 3 6 2r -1 | { x2 } = {3}

⌊ 2 r -1 3r ⌋ { x3 } {5}

Please notice that the parentheses for x1, x2, x3 are only one pair of parantheses and in the same order x1 on the top, x2 in the middle and x3 in the bottom. But as I mentioned they're in one parentheses but I couldn't write

This is the same for the values preceding the Xes and the values after (=) sign

Thank you in advance.

Answer 1

For solving linear systems in Matlab:

To solve Ax = b:

>>x = A\b

Never do this:

>>x = inv(A)*b.
