dear all,

the code is

syms x
f=4*x^4+3*x^3+x^2+x^1+10;
roots=solve(f,x);

I am having problem with 'syms' function in matlab. while running this code I am getting message

"??? Undefined function or method 'syms' for input arguments of type 'char'."

is there any mistake in code? why this is not working?
 

i think u will have to write the function with " " so that matlab will see the f as function of x f(x), otherwise matlab can not tell is f a function of x. have u tried to use the help about the function syms. it's easy to type help syms and will give u everythig about that function, even an exsample how to use it.
 

This error is in 64 bit version of Matlab,then use 32 bit version for using syms
