Question

what is a good matlab code to out put this matrix from question 1 to 3

HITA 1)-The general form cf the quadratic equation is a +bx+c 0 Wrte a MATLAB function named quadratic that finds the two roots of this equation and x when given the coeficients a, b and c 2)-Create a random matrix A in MATLAB with 6 rows and 3 oolumns using the rand) function 3)-Now modify quadratic by so that il can take each row of the matrix A as the inputs a, b and c You can do this by adding a For loop to the function The solution should be displayed as a matrix called output which should have 6 rows and 2 olumns. The values of x, shouild be in the first column and the values of x, should be in the second column

Answer 1

1)

function qudratic()
%to solve qudratic equation of ax^2+bx+c+0

clc;
clear;
fprintf('TO solve qudratic eqauation in the form ax^2+bx+c+0\n');
a=input('enter value of a\n');
b=input('enter value of b\n');
c=input('enter value of c\n');
x1=(-b+(b^2-4*a*c)^0.5)/(2*a);
x2=(-b-(b^2-4*a*c)^0.5)/(2*a);

fprintf('roots of the equation are x1= %f+%fi, x2=%f+%fi\n',x1,imag(x1),x2,imag(x1));   

end

2)

%to generaate random matrix with 6 rows 3 coloum using rand()
%rand(no of rows,no of column)
matrixA=rand(6,3);
fprintf('%d %d %d \n',[matrixA]);

3)

function matrixqudratic()
%to solve qudratic equation of ax^2+bx+c+0
%values are given by a random matrix

clc;
clear;

A=rand(6,3);

for i=1:6
output(i,1)=(-A(i,2)+(A(i,2)^2-4*A(i,1)*A(i,3))^0.5)/(2*A(i,1));

output(i,2)=(-A(i,2)-(A(i,2)^2-4*A(i,1)*A(i,3))^0.5)/(2*A(i,1));

end
output %display result

end
