How does the code you show help you with your objective? It is not Matlab syntax.

There is no single matlab function that will calculate it, but you can
make use of the geometrical theorem that the radius of a circumscribing
circle of a triangle is equal to the product of its three sides divided by
four times the triangle's area.
a = sqrt((x1-x2)^2+(y1-y2)^2); % The three sides
b = sqrt((x2-x3)^2+(y2-y3)^2);
c = sqrt((x3-x1)^2+(y3-y1)^2);
s = (a+b+c)/2;
A = sqrt(s*(s-a)*(s-b)*(s-c)); % Area of triangle
R = a*b*c/(4*A); % Radius of circumscribing circle
