solve ax=b matrix in matlab

To solve the equation ax=b for a matrix x in MATLAB, you can use the backslash operator () or the "mldivide" function. Here's how you can do it:

main.m
% Define the coefficient matrix 'a' and the right-hand side 'b'
a = [1 2; 3 4];
b = [5; 6];

% Solve the equation using the backslash operator (\)
x = a \ b;

% Display the solution
disp('Solution using backslash operator (\):');
disp(x);

% Solve the equation using the "mldivide" function
x = mldivide(a, b);

% Display the solution
disp('Solution using "mldivide" function:');
disp(x);

In this example, the coefficient matrix a is a 2x2 matrix and the right-hand side b is a column vector. The backslash operator () or the "mldivide" function calculates the least squares solution to the equation ax=b and returns the solution vector x. You can then display the solution using the disp function.

Note that the backslash operator () can also be used for solving systems of linear equations with more variables or more equations by providing appropriate dimension matrices.

I hope this helps!
