 Feb 5 awarded Popular Question Jun 6 comment How to tell that 2 set of data are not so difference by using statistical method? @BruceTrumbo 'not so different' means when my data evolve from random number at initial state to stable state which value either 1 or 0 with small fluctuation +-0.2. and after that data will continue move in small fluctuation +-0.2 forever. My point is how to detect when the data go to stable state? note that my data is not matrix but i can plot this data as contour plot using data above with linespace(row) and line space(col).

Apr 1 comment How to solve integrate(exp(x^2)) from 0 to 1 using by Numerical integration/Gauss-Legendre Quadrature? ok now i can get the answer of my program the same with you already but if i change the boundary of integral from (-3, 3) to (0, 1) the result of my program is 0 but In actually it should be 1/2*sqrt(pi)*erf(1) Apr 1 comment How to solve integrate(exp(x^2)) from 0 to 1 using by Numerical integration/Gauss-Legendre Quadrature? sorry sir, Why do you miss w weight on line Gauss-Legendre Quadrature formula and can you write one more line before line 3(0.000146211+0.0352118+0.568889+0.0352118+0.000146211)=1.91881 i didn't know where did these numbers come from. just add one more line thank you.

For integration, i can understand that it can be affect to sign of result because boundary might change (e.g. "from infinity to -infinity" to "from -infinity to infinity") but for Residue Theorem there is only summation How can it affect?
