left division in matlab

In MATLAB, the left division A\B is used to solve the equation A*x=B for x. It is also called the backslash operator. The left division is used when we want to solve a system of linear equations with a coefficient matrix A and a right-hand side vector B.

We can use the left division operator in MATLAB as follows:

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

where A is the coefficient matrix and B is the right-hand side vector.

Here's an example:

main.m
% Solve the system of linear equations
%  2x + 3y = 8
%  4x - 5y = -7

A = [2 3; 4 -5];
B = [8; -7];

x = A \ B
112 chars
9 lines

The output will be:

main.m
x =
   1.0000
   3.0000
24 chars
4 lines

This means that the solution to the system of linear equations is x = 1 and y = 3.
