MATLAB Unexpected Parentheses error

I'm trying to enter this expression in MATLAB, and I get the error:

Error: Unbalanced or unexpected parenthesis or bracket.

y = (exp(t./10)*sin(t.))./(t.^2 + 1)

I'm new to MATLAB and not quite sure what's going wrong there.

Remove the extra dot inside sin(t.).... sin(t). Also, it's a good idea to add a dot before the * operator if you want this to be element-wise, just like the rest of your operations:

y = (exp(t./10).*sin(t))./(t.^2 + 1)

To show that this works:

>> t = 0:10;
>> y = (exp(t./10).*sin(t))./(t.^2 + 1)

y =

  Columns 1 through 7

         0    0.4650    0.2221    0.0190   -0.0664   -0.0608   -0.0138

  Columns 8 through 11

    0.0265    0.0339    0.0124   -0.0146
