function diff = yoursimp(params,X,Y) % This function is called by LSQNONLIN. % x is a vector which contains the coefficients of the % equation. X and Y are the option data sets that were % passed to lsqnonlin. B=params(1); M=params(2); diff = B+M.*X - Y; end
Input argument "params" is undefined. Error in ==> yoursimp at 8 B=params(1);
