what happens is that I create a code that uses Symbolic Math Toolbox but they tell me that in the compiler it does not accept it then I want to declare a symbolic variable without using syms
my code
function pushbutton3_Callback(~, ~, handles)
syms x %variable simbolica x
f=get(handles.edit8,'string');
xl=str2double(get(handles.edit3,'string'));
xu=str2double(get(handles.edit5,'string'));
tol=str2double(get(handles.edit4,'string'));
E=100;
xa=100;
i=0;
while(tol<E)
xr=(xl+xu)/2;
fxl=subs(f,x,xl);
fxr=subs(f,x,xr);
m=fxl*fxr;
if(m)<0
xu=xr;
else
xl=xr;
end
E=abs(xr-xa);
xa=xr;
i=i+1;
end
xr;
vpa(E,5)
set(handles.edit6,'string',xr);
set(handles.edit9,'string',E);
