    <p>I am working with a triangulation program and I need to plot the data points and their triangulation (obtained from another program). So I have my delauany edges matrix <strong>newgrid1_eDT</strong> (e for edge list) as (first column is line number):</p> <pre><code>1 0 0 9 2 0 1 9 3 0 1 9 4 0 1 8 5 0 1 8 [...] 11716 5 6 8 11717 1 2 4 11718 0 2 4 </code></pre> <p>and the idea is to make it like this newgrid1_ASCIIeDT:</p> <pre><code>1 0 0 9 2 0 1 9 3 4 0 1 9 5 0 1 8 6 7 0 1 8 [...] 11715 5 6 8 11716 11717 1 2 4 11718 0 2 4 </code></pre> <p>Basically, each 2 rows represent a 3d coordinate pair (and each pair of points represents a line).</p> <p>I have written the following in an attempt to copy two rows (index i) consecutively from <strong>newgrid1_<em>eDT</strong> followed by a blank line to <strong>newgrid1</em>_ASCIIeDT</strong> (index j), thus looping through the empy matrix <strong>newgrid1_<em>ASCIIeDT</strong> filling it gradually. I have allocated 11718+ 11718/3 =15624 rows in the recieving matrix <strong>newgrid1</em>_ASCIIeDT</strong>; one for each point we tranfer over from <strong>newgrid1__eDT</strong> plus one empty mrow after every 2 lines (at rows 3,6,9,... and so on):</p> <pre><code>newgrid1__ASCIIeDT=zeros(15624,3); [m,l]=size(newgrid1__ASCIIeDT) ; j=0; i=1; for j = 1:3:15624 i newgrid1__ASCIIeDT(j,:)=newgrid1__eDT(i,:); newgrid1__ASCIIeDT(j+1,:)=newgrid1__eDT(i+1,:); newgrid1__ASCIIeDT(j+2,:)=blank; i=i+1 end </code></pre> <p>For some reason I am convinced this should do the trick but somehow I get weird results. Are there any other (simpler ways) of doing this or am I reinventing the wheel?</p> <p>Ideally I would have written this in C (where all the other stuff is happening) but I just need a quick fix at the moment and cant go through 11k lines to introduce blank lines. Any help please ?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
