Matlab keeps rounding my outputted values in the command window to 4dp, I've looked all over mathworks and I can't find a solution to my problem in particular. Does anyone know how I can fix this?
syms x n
f(x) = (2/sqrt(pi))*symsum(((-1)^n * x^(2*n +1))/((2*n+1)*factorial(n)),n,0,100);
f(0.1)
ans =
0.1125

Hi John,
Assuming you have set the preference option "FloatingPointOutput" to true in sympref, the output will be fixed-decimal format with 4 digits after the decimal point. If you need to change the number of digits after the decimal point, consider using vpa function with the number of significant digits you need.
Hope this helps.
