Error with "syms" function
显示 更早的评论
Hello,
I now have 2 quadratic equations with 2 known and 2 unknown.
(x1-xc)^2+(y1-yc)^2=R^2
(x2-xc)^2+(y2-yc)^2=R^2
I know the values for x1,x2,y1,y2 and R, these can be input manually in the script. I need to find xc and yc. Based on a recommendation I wrote the below script to find xc and yc-
syms xc;
syms yc;
[x y] = solve('(x1-xc)^2+(y1-yc)^2=R^2 ,(x2-xc)^2+(y2-yc)^2=R^2')
But I get the below error message
??? Undefined function or method 'syms' for input arguments of type 'char'.
Can anybody please help me with this error message

It means that you either do not have the symbolic toolbox installed or else you do not have it licensed. Use the command
ver
to find out what you have installed.
