MATLAB: “A MATLAB string constant is not terminated properly”-what this error indicates?

string constant

F2= inline('(A1*(sqrt(pi)*(P1/m3)*exp(P1^2)*(erf(P1+(f2./sqrt(2/m4)))-erf(P1)))+(A2/m4)*...
 (1-exp(-m3*f2-m4*(f2.*f2/2))-m3*((A1*(sqrt(pi)*(P1/m3)*exp(P1^2)*(erf(P1+(f2/sqrt(2/m4)))-erf(P1))))./A1))... +A3*(sqrt(pi)*(P2/m3)*exp(P2^2)*(erf(P2+(f2/sqrt(2/(m4+2*m1))))-erf(P2)))).*exp(m5.*f2.^2)','f2');
here only f2 is variable except this all other are constant.

It indicates that there is a blip too few, too many, or in the wrong place. However, you code looks ok to me.
Comments:
  • Why did you choose inline and not an anonymous function?
  • I find it easier to get strings like this one right if I split it into substrings and concatenate these in a final step
Something like this is easier to get right, to read, and to maintain.
