The total number of pixels is not equal to the sum of values in your image. sumOfAllPixelValues = sum(double(rgbImage(:))); numberOfPixels = numel(rgbImage); The size on disk of an image is numberOfPixels*bytesPerPixel, where bytesPerPixel depends on the bit depth of an image (uint8 would be 8 bits=1 byte, for example. To downsample the image by half, … Read more
You need to do this: foreach ($menu_items as $item=>$value) { if($item != ‘about-me’){ echo ‘<a href=”#’.$item.'”>’.$value.'</a>’; //change here }else if($item == ‘about-me’){ echo ‘<a href=”#’.$item.'”>about</a>’; } } You are using $item, use the $value instead of $item. 0 solved How can I show array in PHP?
Let Px be the probability that the game ends in position 3 if it starts in position x. We know that P3=1 and P7=0 If you start in any other cell, then after you move you are essentially beginning the game again in the new cell. The probabilities for the other 7 cells can therefore … Read more
That graph is a SED or spectral energy distribution graph or plot from NASA/IPAC Extragalactic Database. More information is here . It has error bars displayed on the plot, but not point labels. Not all SED plots look like this one, so lets describe the features this one has Graph Title Scatterplot X axis label … Read more
Erm, no. That’s part of the PHP syntax. Not really any way around it. In response to the edit: There would be no way for the IDE to know what is a variable and what isn’t. I suppose you could use your own symbol in replace of a $ and then replace all instances of … Read more
Scan the borders of the image and when you find a white pixel flood fill with black. You will want something like: uchar white(255); // do top and bottom row for(int y = 0; y < image.rows; y += image.rows-1) { uchar* row = image.ptr<uchar>(y) for(int x = 0; x < image.cols; ++x) { if(row[x] … Read more
putchar(charInput) will print your character once, and will then return its argument, charInput. This then gets passed to printf, which prints the same character again. solved Printing a char in ANSI C
char represents a character (allocated on the stack). If you want to set it to empty, use char c=”\0″ or char c = (char) 0. char* cPtr is a pointer to a character. You can allocate an empty character on the heap with char* c = new char(‘\0’). char c[n] is a character array of … Read more
Following code can do the grouping by date var obj = [{ “message”: “fsbdfs”, “id”: “8290”, “readBy”: “2016-05-25 06:17:01”, “userID”: “339”, “dateTime”: “2016-05-25 06:16:32” }, { “message”: “Hi”, “id”: “8291”, “readBy”: “2016-05-25 6:33:52”, “userID”: “332”, “dateTime”: “2016-05-25 06:17:06” }, { “message”: “nbfsdbf”, “id”: “8292”, “readBy”: “”, “userID”: “339”, “dateTime”: “2016-05-25 07:03:44” }, { “message”: “jsdhfjsdhf”, … Read more
In haskell: [(x, y) | x <- [1..40], y <- [1..40]] In other languages you should probably look at for-loops: (this is C#) Tuple<int, int>[,] things = new Tuple<int, int>[40,40]; for (int i = 0; i < 40; i++) { for (int j = 0; j < 40; j++) { things[i,j] = Tuple.Create(i+1,j+1); } } … Read more
If this two column are same data type , you can just union a = predictons_lr.select(‘prediction’) b = predictions_nb.select(‘prediction’) new_df = a.union(b) 4 solved How to create a dataframe from two others dataframe?
try in this way private static Random rand = new Random(); color= Color.FromArgb(this.rand.Next(256), this.rand.Next(256), this.rand.Next(256)); refer here for documentation about Color.FromArgb you can create the color in 3 differents overloads with this function (using only int32) one integer –> Creates a Color structure from a 32-bit ARGB value. three integers –> Creates a Color structure … Read more
What you are asking for cannot be handled in the executable. The console is launching the executable and not waiting for it to exit. That is a console issue, not an executable issue. You need to use the console’s start command to run the executable so you can use the command’s /wait parameter: start /wait … Read more

For loops are iterative statements that repeat a certain block of code , on the other had, if statements are the conditional statements that perform decision making situations. You cannot go from one to other as just as you can’t go from repeating stuff and making decisions in most cases. However, if you wanna repeat … Read more
