My problem with simple function input in matlab? Error:Line -3

I am trying to input my function for integration, and every time I try and make a function and define it, I always get the same error, it says "???Error: Line: -3{??? Undefined function or variable 'x'" but when I input the same function in maple, the same exact way, I get no error, so what am I doing so wrong with matlab??
example function y = x+1;
matlab in return says
Version 7.12.0.635 (R2011a) 32-bit (glnx86)
???Error: Line: -3{??? Undefined function or variable 'x'.
y = x+1 }

Maple and matlab have different syntax. see https://www.math.duke.edu//education/ccp/materials/diffeq/mlabtutor/mlabtut9.html for some good examples of how to integrate in matlab

thanks, thats exactly what I was missing, the argument of syms x, obviously my function is a little more complicated than y=x+1, but for ease of typing and ease of answer, i used the most basic function. Thanks for your very fast response and link!
my integral is actually (x^2-2*x-1)/(((x-1)^2)*(x^2+1)). I know I have a lot of (), but this way I dont lost track of where my arguments go. Thanks Again
