Create a Matlab Mfile to solve an nn system of equations usi

Create a Matlab M-file to solve an n*n system of equations using Cramer’s method. It should be a function which takes coefficients of the system and constant terms as user input and gives the values of unknowns.

Solution

program:

clc
clear all
n=input(\' enter number of variables\');
e=input(\'number of equations\');
if (n>e || n<e),
    disp(\'system is inconsisstent\');
else
    disp(\'system is consisstent\');
    disp(\'enter the constants of the equation one bye one\')
    for i=1:n,
        for j=1:n,
            A(i,j)=input(\'enter the coeficents one by one=\');
        end
        b(i)=input(\'enter equation right side constant=\');
        disp(\'go for the next equation\');
    end
    if det(A)==0,
        disp(\'no solution\');
    else
    for i=1:n,
        s=A;
        s(:,i)=b;
        x(i)=(det(s)/det(A));
        disp(\'x\');
    disp(x);
    end
    end
  
end

result:

enter number of variables2
number of equations2
system is consisstent
enter the constants of the equation one bye one
enter the coeficents one by one=1
enter the coeficents one by one=2
enter equation right side constant=3
go for the next equation
enter the coeficents one by one=4
enter the coeficents one by one=5
enter equation right side constant=6
go for the next equation
