find a solution to the following set of equations x + 2y + 3z = 12 −4x + y + 2z = 13 9y − 8z = −1 in matlab

In Matlab, we can solve linear equations using the backslash operator to solve equations of the form Ax = B.

To find a solution to the following set of equations x + 2y + 3z = 12, −4x + y + 2z = 13, and 9y − 8z = −1 in Matlab, we can define the matrix A and column vector B as:

main.m
A = [1 2 3;
    -4 1 2;
    0 9 -8];

B = [12; 13; -1];

Then, we can solve for x using the backslash operator:

main.m
x = A \ B
10 chars
2 lines

The output x will be a column vector of the solution to the set of equations.

Full code:

main.m
A = [1 2 3;
    -4 1 2;
    0 9 -8];

B = [12; 13; -1];

x = A \ B
