Grouping matrix rows in terms of one column

由 ε祈祈猫儿з 提交于 2019-11-27 19:32:02
问题 First of all it is really hard for me to describe the problem really good but I'll try. Say that we have matrix A A = [23 1; 45 1 78 1 86 1 98 2 1 2 23 2 14 3 15 4 85 4] What I want as an output is B{1} = [23,45,78,86] B{2} = [98,1,23] B{3} = [14] B{4} = [15,85] Bear in mind that the original A is a huge matrix, and I do not wanna do this with for loops. I would like to use functions that uses parallel processing. 回答1: You could use accumarray here: B = accumarray(A(:,2),A(:,1),[],@(x){x},{})

Convert cell array of cells into cell array of strings in MATLAB

问题 Using regexp with tokens on cell array of strings I've got cell array of cells. Here is simplified example: S = {'string 1';'string 2';'string 3'}; res = regexp(S,'(\d)','tokens') res = {1x1 cell} {1x1 cell} {1x1 cell} res{2}{1} ans = '2' I know I have only one match per cell string in S. How I can convert this output into cell arrays of strings in a vectorized form? 回答1: The problem is even worse than you thought. Your output from REGEXP is actually a cell array of cell arrays of cell arrays

Grouped UITableview remove outer separator line

由 限于喜欢 提交于 2019-11-27 18:05:30
I have a grouped UITableview which is created programatically. Also I have a cell with xib file populated in tableview programmatically as well. So far so good. But I want to only remove outer separator line. I used below code but this time removed all separator line. self.tableView.separatorColor = [UIColor clearColor]; this is not good option for my situation. Here is the screenshot what i want to do; Qi Lee I just worked out a solution, as the cell has contentView which is a UIView , so I think you can just focus on the bottomline of contentView . Here is my code: first, you have to make

How do i handle cell double click event on WPF DataGrid, equivalent to windows DataGrid's Events?

由 时光怂恿深爱的人放手 提交于 2019-11-27 16:33:45
问题 As you know, in windows C#'s gridview, if we want to handle a click/double click event on cell then there are events like CellClick, CellDoubleClick, etc. So, i wanna do same like as windows gridview with WPF DataGrid. I have searched so far but neither answer is applicable nor useful. Some of them says use the MouseDoubleClick event but, in this event, we have to check for each row as well as item in that row, so it is time consuming to check every cell for data and timing is most important

How can I create a footer for cell in datagridview

由 帅比萌擦擦* 提交于 2019-11-27 16:18:33
I need to create a DataGridView with cells that have two parts. One part is the content of that cell such as 0, 1 etc value. And the remain part is the footer of that cell, just like a footer of a word document, refers to the ordinal number of that cell. I can not enclose any images so the question may be ambiguous. Anyways thanks in advance. To create DataGridView cells with extra content you need to code the CellPainting event. First you set up the cells to have enough room for the extra content and layout the normal content as you wish..: DataGridView DGV = dataGridView1; // quick reference

How can I concatenate strings in a cell array with spaces between them in MATLAB?

由 ⅰ亾dé卋堺 提交于 2019-11-27 16:09:09
问题 I want to concatenate (padding with spaces) the strings in a cell array {'a', 'b'} to give a single string 'a b' . How can I do this in MATLAB? 回答1: You can cheat a bit, by using the cell array as a set of argument to the sprintf function, then cleaning up the extra spaces with strtrim: strs = {'a', 'b', 'c'}; strs_spaces = sprintf('%s ' ,strs{:}); trimmed = strtrim(strs_spaces); Dirty, but I like it... 回答2: matlab have a function to do this, ref: strjoin http://www.mathworks.com/help/matlab

javafx GridPane retrieve specific Cell content

由 旧时模样 提交于 2019-11-27 15:30:31
I want to retrieve the content of one specific cell in a Gridpane. I have put buttons in the cells with the setConstraints(btt , 0 ,1 ) setConstraints(btt , 0 ,2 ) getChildren().add.... In my case the GridPane.getChildren.get(10) is not good. I want to go directly to the cell(4,2) and get its content. Well I guess if there is no solution to get a specific node from gridpane by is column and row index, I have a function to do that, private Node getNodeFromGridPane(GridPane gridPane, int col, int row) { for (Node node : gridPane.getChildren()) { if (GridPane.getColumnIndex(node) == col &&

JAVA: Put Image in jTable Cell

I need to display an image in one of jTable cells. I wrote this: class ImageRenderer extends DefaultTableCellRenderer { JLabel lbl = new JLabel(); public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { lbl.setText((String) value); lbl.setIcon(new ImageIcon("/home/ariyan/Desktop/71290452.jpg")); return lbl; } } and then used it as this: jTable1.getColumn(0).setCellRenderer(new ImageRenderer()); But this didn't work How I can do that? Thanks JTable already provides a default renderer for images. You just need to

How do you specify table padding in CSS? ( table, not cell padding )

由 梦想与她 提交于 2019-11-27 14:28:50
问题 I have a table with a colored background and I need to specify the padding between the table and it's content, I.E. cells. The table tag doesn't seem to accept a padding value. Firebug shows the table and tbody's layout with padding 0 but doesn't accept any value entered for them, so I guess they just don't have the padding property. But the thing is I want the same separation between cells than the top cells with the table top and the bottom cells with the table's bottom. Again, what I want
