python - Wireframe plots -


the program calculates reflection coefficient of multilayer system, depending on thickness of 50 layers (d1, d2). if take 2 numbers (d1,d2), works correct. need wireframe plots, d1, d2 takes meaning in range, error: "valueerror: input must square array" in line 13. how can fix it?

from math import pi import numpy np import matplotlib.pyplot plt  def r(n1, n2, d1, d2, lamda):     phy1 = (-2*pi*n1*d1/lamda)     phy2 = (-2*pi*n2*d2/lamda)     dpd1 = 0.5*np.array([[2*np.cos(phy1),   2j*np.sin(phy1)/n1],    [n1*2j*np.sin(phy1),  2*np.cos(phy1) ]])     dpd2 = 0.5*np.array([[2*np.cos(phy2),   2j*np.sin(phy2)/n2],   [n2*2j*np.sin(phy2),  2*np. cos(phy2) ]])     d0 = 0.5 * np.array([[1, 1], [1, -1]])     ds = np.array([[1, 1], [n1, -n1]])     dpd = np.dot(dpd1, dpd2)     dpd = np.linalg.matrix_power(dpd, 50)     m = np.dot(d0, dpd)     m = np.dot(m, ds)     return(abs(m[1,0]/m[0,0])**2)  x = np.arange(0, 10, 1) y = np.arange(0, 10, 1) x, y = np.meshgrid(x, y) z = r(0.99910053+0.00183184j,  0.92373900+0.00644652j, x, y, 13.5) fig = plt.figure() ax = fig.gca(projection='3d') surf = ax.plot_wireframe(x, y, z, antialiased=true)

i don't know how without loop. here solution:

from math import pi import numpy np import matplotlib.pyplot plt mpl_toolkits.mplot3d import axes3d  def r(n1, n2, d1, d2, lamda):     phy1 = (-2*pi*n1*d1/lamda)     phy2 = (-2*pi*n2*d2/lamda)     dpd1 = 0.5*np.array([[2*np.cos(phy1),   2j*np.sin(phy1)/n1],    [n1*2j*np.sin(phy1),  2*np.cos(phy1) ]])     dpd2 = 0.5*np.array([[2*np.cos(phy2),   2j*np.sin(phy2)/n2],   [n2*2j*np.sin(phy2),  2*np. cos(phy2) ]])     dpd = np.dot(dpd1, dpd2)     dpd = np.linalg.matrix_power(dpd, 50)     d0 = 0.5 * np.array([[1, 1], [1, -1]])     ds = np.array([[1, 1], [n1, -n1]])     m = np.dot(d0, dpd)     m = np.dot(m, ds)     return(abs(m[1,0]/m[0,0])**2)  x = np.arange(0, 10, 1) y = np.arange(0, 10, 1) x, y = np.meshgrid(x, y) z = np.zeros(x.shape).ravel() i, (x, y) in enumerate(zip(x.ravel(), y.ravel())):     z[i] = r(0.99910053+0.00183184j,  0.92373900+0.00644652j, x, y, 13.5) fig = plt.figure() ax = fig.gca(projection='3d') surf = ax.plot_wireframe(x, y, z.reshape(x.shape), antialiased=true) plt.show()

asynchronous - C# WinSCP .NET assembly: How to upload multiple files asynchronously -

i using winscp .net assembly uploading files. want upload multiple files asynchronous way. have created method works single upload. public class uploadingdata { private sessionoptions _sessionoptions; private session _session; //connection etc private void onconnected() { foreach (var fileinfo in localfileslist) { var task = task.factory.startnew(() => uploadfilesasync(fileinfo)); } } private async task uploadfilesasync(string file) { string remotefilepath = _session.translatelocalpathtoremote(file, @"/", "/test_data_upload"); var uploading = _session.putfiles(file, remotefilepath, false); //when done await task.run(() => thread.sleep(1000)); } } please suggest me correct way. thanks you can use backgroundworker class this: string[] images = new string[50]; foreach (var path in images) { backgroundworker

asp.net - Problems sending emails from forum -

i have been redesigning site has message board, has been written guy looked after site. it has few problems , written in .asp , uses .mdb files database. you can see whole thing here . feel free post if helps, test thing have set using original files , new database. the basic problem when posts message, supposed email sent them, have posted it. when replies, originator supposed message, replier has been posted. i’d have thought @ point in process there should script/file in postmessage.asp? the postmessage.asp page below. <% option explicit %> <!-- #include virtual="common/adovbs.inc" --> <html> <head> <meta http-equiv="content-type" content="text/html; charset=windows-1252"> <meta name="generator" content="microsoft frontpage 4.0"> <meta name="progid" content="frontpage.editor.document"> <title>new page 2</title> <base target="_self"
