expected output

model = gt-n8000, cordova_version = 3.6.4, os = android

hello trying make 1 string shown below display values not name of values .i not able attribute , = in striing here code

var deviceinfo = ''  var deviceinfo = '';  deviceinfo += model = getmodel() + ','; deviceinfo += cordova_version = cordovaversion() + ',';  deviceinfo += os = getos();  alert(deviceinfo); function getmodel() {     return "gt-n8000" } function cordovaversion() {     return "3.6.4" } function getos() {     return "android" }

try below code.

var deviceinfo = ''  var deviceinfo = '';  deviceinfo += 'model = ' + getmodel() + ','; deviceinfo += 'cordova_version = ' + cordovaversion() + ',';  deviceinfo += 'os = ' + getos() + ',';  alert(deviceinfo)  function getmodel() {     return "gt-n8000" }  function cordovaversion() {     return "3.6.4" }  function getos() {     return "android" }

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
