"Undefined function 'equationsToMatrix' for input arguments of type 'sym'." Error

10 views (last 30 days)
Hello all,
I've been trying to deal with the equationsToMatrix function, but getting this "Undefined function 'equationsToMatrix' for input arguments of type 'sym'." error all the time.
To try, I took a sample code from Help. It gives the same error also.
syms x y z
[A,b] = equationsToMatrix([x+y-2*z==0,x+y+z==1,2*y-z+5==0], [x,y,z])
Any ideas? Version is 2014b.
BR, Ozgur

I think this is related to couple of issues combined. MATLAB was on E:\ drive, I'd uninstalled and installed it again on C:\.
I've made toolbox path cache update afterwards. Now it is working.
P.S.: After posting this question, I realized that most of the symbolic functions gone crazy. This problem is not directly related to equationsToMatrix function.
Thanks for the replies.

The code works for me.
Do you have symbolic toolbox installed?

When I run your code (using R2014b) I get
A=[1,1,-2;1,1,1;0,2,-1]
b=[0;1;-5]
