问题 How can one perform computations in MATLAB that involve large numbers. As a simple example, an arbitrary precision calculator would show that ((1/120)^132)*(370!)/(260!) is approximately 1.56, but MATLAB is not able to perform such a computation ( power(120,-132)*factorial(370)/factorial(260) = NaN ). I have also tried the following, which does not work: syms a b c d; a=120; b=-132; c=370; d=260; f=sym('power(a,b)*gamma(c+1)/gamma(d+1)') double(f); % produces error that instructs use of `vpa`

问题 I am looking for an approach to debugging this scenario. I have verified in Fiddler that there is no HTTP response at all. To be clear, as I understand it a controller method should not simply hang, there is no exception. I have verified the lack of response in Fiddler. The method returns a valid object, verified by stepping through the code to the final return statement. This is different from the original question in that the controller method is hit, and was not before. The reason for this

问题 Im not sure what to do here. I've looked at the logcat cat and I know that its between my MainActivity class and my DrawingTools class. I've also listed the line numbers to help identify which lines are which. My question is how do I fix this error java.lang.StackOverflow? Here is my Logcat: 07-05 00:55:17.852: E/AndroidRuntime(15504): FATAL EXCEPTION: main 07-05 00:55:17.852: E/AndroidRuntime(15504): java.lang.StackOverflowError 07-05 00:55:17.852: E/AndroidRuntime(15504): at java.lang.ref

问题 Do we have some set of rules when we should abstain of using FetchType.EAGER ? I have heard that some of JPA frameworks (eg. Hibernate) should resolve cyclic dependencies. Do we have some advice when it comes risky to relay on frameworks? Do StackOverflowError along with FetchType.EAGER is always about bug in framework(I mean if I have like 3 rows in two tables)? 回答1: One good reason to avoid FetchType.EAGER is that you can always enable eager fetching manually in JPQL (with JOIN FETCH ), but

问题 Previous question here: stack overflow with Google maps API (IE7 IE8) I found the following question in the mean time: Google Maps API v3: Can I setZoom after fitBounds? The solution there works just fine, when I have more than one marker on the map. However when I visit a subpage of groupbke.young.netaffinity.net eg. https://groupbke.young.netaffinity.net/hotels/ireland/dublin/dublin/young-testing-hotel-liege/specials/bed-and-breakfast the map will only load if map.fitBounds() is called. On

问题 I am trying to write simple example with google maps and markers but i faces with error: Uncaught RangeError: Maximum call stack size exceeded js: $(document).ready(function() { var map; var elevator; var myOptions = { zoom: 1, center: new google.maps.LatLng(0, 0), mapTypeId: 'terrain' }; map = new google.maps.Map($('#map_canvas')[0], myOptions); var markers = []; coords = [{ lat: 55, lng: 37 }]; for (var x = 0; x < coords.length; x++) { var latlng = new google.maps.LatLng(x.lat, x.lng); var

问题 I've been fighting an issue with google maps on our site which occurs on first load on IE7 and IE8. I was trying to deal with the solution by combining firefox and ie8 debuggers, but it's quite difficult (and my boss is pushing me on other issues as well) as the JS is minified and IE debugger cant do a thing about it. We have two versions of the same site, one at irelandhotels.com and the dev environment at groupbke.young.netaffinity.net. First one has 500+ markers, the dev environment only 5

问题 I've stubled upon a function (here on SO) which writes a file, but makes sure to not overwrite a file: function writeFile(i){ var i = i || 0; var fileName = 'a_' + i + '.jpg'; fs.exists(fileName, function (exists) { if(exists){ writeFile(++i); } else { fs.writeFile(fileName); } }); } Now there is an interesting comment below which says: Minor tweak: Since JavaScript doesn't optimize tail recursion away, change writefile(++i) to process.nextTick(function(i) {writefile(++i);}); that will keep
