could someone help me please?
I would like to obtain the quadratic curve coming from the calculation of a 2x2 matrix determinant.
This is what I wrote in my code:
h = @(x,y,z) 3.*(x+5).^2 + (x + 5).*(y - 2) + (y - 2).^2;
syms x y z
w = h(x,y,z)
g = @(x,y,z) (x - 5).^2 - (x - 5).*(y - 3) + (y - 3).^2;
Now I should do the difference between exp1 and exp2, but I can't do it.
I am new with the symbolic toolbox, so I have difficulties to pass from symbolic expressions to numerical values.
I guess there is a faster way to calculate the determinant of my matrix and thus get the quadratic function but I don't really know how to find it.
Thank you very much for your support!
