Can you help me rewrite my matlab code to mathematica code?
Hello all, Rectntly, i wrote a code using matlab. in the code written by me, i use a function erf(x), while the x used by me is complex arguments, so the matlab cannot give the results. i realized that the mathematica can realize this. I'm a green hand in Mathematica, so I cannot rewrite my matlab code to Mathematica. the matlab code written by me is attached in "http://www.mathworks.com/matlabcentral/newsreader/view_thread/172809". is there anyone can help me rewrite the code using Mathematica. the function i need to plot 3D is the abs(Ik(x,y)) Ik is the integration of ik(theta) from 0 to 2*pi. and ik(theta)=3/(2*pi)*sin(theta)^2*[1/(2*M)+sqrt(pi)/4*N/ [M]^(3/2)*exp(N.^2/4./M)* [1+erf(N/[2.*sqrt(M)])]]; M=(4*cos(theta)^2+9.*sin(theta)^2)/4+i*z; N=i*(x*cos(theta)+y*sin(theta)); z is constant, and we can given z=5; and want to plot the 3D picture of the absolute value of Ik in the xy plane. The x and y is from 20 to 20. Thanks, Dajun Liu
