Question

MATLAB 2017b

Write a program which will:

Accept three numbers from the user: a, b and c which can assume any value.

Accept Dx and Dy for the calculations of the function

Write a function which accept a, b, c, Dx and Dy and will draw the following surface

Where x and y vary in the range of -10?x?10 -10?y?10.

Allow the user to rerun the program and exit the program upon request.

Answer 1

Code

clc
clear all
while(1)
a=input("Enter Value of a=");
b=input("Enter Value of b=");
c=input("Enter Value of c=");
Dx=input("Enter Value of Dx=");
Dy=input("Enter Value of Dy=");

myfunction = @(x,y) (a*x.^2 + b*y.^2+c*x+Dx*Dy);
[X,Y] = meshgrid(-10:.5:10);

Z = myfunction(X,Y);
surf(X,Y,Z);
colorbar;
xlabel("X value");
ylabel("Y value");
zlabel("Function");

m=input('Do you want to rerun code, Y/N [Y]:','s');
if m=='N'
break
end

end

Output:-

Enter Value of a=0.5
Enter Value of b=22
Enter Value of c=0.75
Enter Value of Dx=1
Enter Value of Dy=25
Do you want to rerun code, Y/N [Y]:
