How to make contour plot from this function in MATLAB R2013a?

f(x,y)= x^5 + x^4- 2x^2 y + y^2

Answer 1

[KSSV]

f = @(x,y) x.^5 + x.^4- 2*x.^2.*y + y.^2 ;

N = 100 ;
x = linspace(0,1,N) ;
y = linspace(0,1,N) ;
[X,Y] = meshgrid(x,y) ;

Z = f(X,Y) ;
contour(X,Y,Z,100)

Where do you get the value of N? And also the 0,1 on the right side of x and y.

[KSSV]

To get the function solved, you need to have x,y values. (0,1) is the range of x and y I gave. N = 100, it divides (0,1) interval into 100 points. Read about linspace.

I see, thank you very much. But, there is an error "unexpected matlab operator", do you know how to fix it?

[KSSV]

Where is the error? The given code works fine. Show us the code, if you have made any changes.
