i'm trying shift axes positions in matlab figure. i'd achieve similar (which done in gnuplot): i don't have idea whether possible @ all, or might find answer, appreciated. hmm.... so let's plot: x = zeros(1,21); y = -10:10; z = y/2; figure; plot3(x,y,z); % line (0,-10,-5) (0,10,5) similar example well, 1 problem matlab doesn't automatically plot coordinate axis you've shown there. discussed here: how show x , y axes in matlab graph? to plot (in 3d), cheap solution is: locs = axis; % current axis boundaries hold on; plot3([locs(1) locs(2)], [0 0], [0 0]); %plot xaxis, line between(-x,0,0) , (x,0,0); plot3([0 0], [locs(3) locs(4)], [0 0]); %plot y axis, line (0,-y,0) , (0,y,0); plot3([0 0], [0 0], [locs(5) locs(6)]); % plot z axis hold off just gnu plot, 3d matlab plot "in box." unlike gnu plot, matlab box isn't outlined. if want outline you'll have draw lines too...ugh. % lets plot 12 lines make box in black

i'm learning data validation of cell values in excel , have discovered problem solve. have cell want allow specific number values. no problem since can use data validation specific cell. can't use "numbers" criteria have numbers 10; 20; 30 example because can specify number ranges (larger than, less than, between etc). instead of using number range use "list" function , write 10; 20; 30 , works. the problem occurs when add special formatting cell. let's want format 1 isn't pre-existing in excel, enter value "10" should display "10 moneys" or grammatically correct. if use custom formatting can add " moneys" after "standard" displayed in cell format menu (ctrl + 1). if either 1 works, if add both list 10; 20; 30, , formatting of standard" moneys" doesn't work when use drop down menu. reason because drop down menu tries add value "10 moneys" , list doesn't recognise because expe

i wonder if there way "debug" modelica code, mean debugging code line line , can see how variables change, things that? i know modelica code translated c, want know if there's possibility somehow, if there is, believe it's gonna great improvement of simulation environments. thanks. hy this question , comes lot. first, let's step second. the idea of debugging "line line" comes imperative programming languages. "imperative" mean program sequence of instructions carried out in specified order. when debugs java or python, "line line" approach makes sense because statements fundamental way behavior represented. "line line" approach extended modeling formalisms block diagrams (e.g. simulink) because, while graphical, imperative (i.e. constitute steps carried out in specified order). but modelica not imperative language. there no notion of steps, statements or instructions. instead, have omnipresent equ

i using armadillo symmetric , triangular matrices. wanted efficient in terms of memory storage. however, seems there no other way create new mat , fill zeros(for triangular) or duplicates(for symmetric) lower/upper part of matrix. is there more efficient way of using triangular/symmetric matrices using armadillo? thanks, antoine there no specific support triangular or banded matrices in armadillo. however, since version 3.4 support sparse matrices has gradually been added. depending on armadillo functions need, , sparsity of matrix, might gain using spmat<type> implements compressed sparse column (csc) format . each nonzero value in matrix csc format stores row index along value not save memory triangular matrix. banded diagonal matrix should consume less memory.

i configured our implementation use azure caching provider maintain session state between cloud instances described here: http://msdn.microsoft.com/en-us/library/windowsazure/gg185668.aspx this created new startup task on csdef file fails error: c:\program files (x86)\msbuild\microsoft\visualstudio\v11.0\windows azure tools\2.0\microsoft.windowsazure.targets (987): cloudservices64 : cannot find file named 'approot\bin\microsoft.windowsazure.caching\clientperfcountersinstaller.exe' startup task microsoft.windowsazure.caching\clientperfcountersinstaller.exe install of role myrole.web. the .exe in nuget package , in main folder included in source control tfs uses deployment. i found previous question addresses same issue: azure deployment error: cannot find clientperfcountersinstaller.exe but accepted answer states delete startup task installs .exe needed caching take place. make sure .exe marked copyalways copied \bin directory. to so, right click on .e

i've been doing research topic , haven't found concrete answers. let's have these expression in code: b = 2 … b = b + 5 … b = j + b … (these simple examples, know aren't realistic) b has many different values throughout these lines. in line 1 it's 2 , later on becomes 7 , , more later on it's 7 + j . compiler need keep track of these different values b , 1 way rename them. example, when b redefined b = b+5 , changed b1 = b+5 . last redefinition b2 = j+b1 . the motivation behind idea involves optimizing program i'm building. involves replacing variables expressions they're related to. if variable redefined, however, character 'b' can mean multiple things @ once. method i'm using keep track of things i've described above, redefining variable names. is @ how compiler's work? there name this? i'm trying find out as can process of compiler redefining variables in case of redefining variables. if helps, believe done

i'm using vb.net 2010 how data series on chart array or textbox or table ? i'm using code plot graph: serie1.points.addxy(val(label4.text), val(label5.text)) i need read values serie1 . you store values in list while adding series or if want access after adding series following. using system.windows.forms.datavisualization.charting; datapoint[] arr = series.points.toarray<datapoint>(); or list<datapoint> lst = series.points.tolist<datapoint>(); and can access x , y values using foreach loop foreach(var pt in lst) { pt.xvalue // access xvalue pt.yvalue // access yvalue }

here code jquery ui: jquery("#nodeliverydate").dialog({ resizable:false, draggable:false, modal:false, buttons:[{text:"close",click:function(){jquery(this).dialog("close");}}] }); it simple code using jquery dialog alert box. defined 1 button close dialog. however, runs in odd way dialog contain many buttons, , text on buttons function names such "each","all","clone","select","size", etc . , after close it, if dialog shows again, normal. have idea why happens? jquery("#nodeliverydate").dialog({ modal: true, title: 'delete msg', zindex: 10000, autoopen: true, width: 'auto', resizable: false, buttons: { yes: function () { // $(obj).removeattr('onclick'); // $(obj).parents(&

if going create app alerts, users can post little messages traffic, crimes, , other news, how difficult and/or if implement sort of compiler analyze each piece of msg, , categorize in sections crime/murder or traffic/reallyslow. i think easier approach obligate user select appropriate category more appropriate: create table alert{ id_alert int not null primary key auto_increment, alert varchar(255), id_sub_category, foreign key(id_sub_category) references sub_category(id_sub_category) } create table sub_category{ id_sub_category int not null primary key auto_increment, sub_category varchar(45), id_category, foreign key(id_category) references category(id_category) } create table category{ id_category int not null primary key auto_increment, category varchar(45), } i need advice how difficult implement first approach the database design seems appropriate enough, not knowing final solution needed. your ultimate question has nothin
