solve set of linear equations in matlab

To solve a set of linear equations in MATLAB, you can use the backslash operator \ or the linsolve function. Here's an example using the backslash operator:

main.m
% system of equations: 2x + 3y - z = 1, x - y + 2z = -3, 3x + 2y - 4z = 7
A = [2 3 -1; 1 -1 2; 3 2 -4];  % coefficient matrix
B = [1; -3; 7];  % right-hand side vector
X = A \ B;  % solution vector
disp(X);  % display the values of x, y, z
240 chars
6 lines

This will output the solution vector X:

main.m
X =
   1.0000
  -1.0000
  -2.0000
34 chars
5 lines

Alternatively, you can use the linsolve function:

main.m
X = linsolve(A, B);
disp(X);
29 chars
3 lines

This will also output the solution vector X. Note that the linsolve function can handle special cases, such as singular matrices or overdetermined systems.
