How can I center the text printed by display('the text')?
Eg, like the text you get when entering matlab.
A function to get the width of the current terminal will do to (I'll figure it out from there).
with a fairly new version of matlab you can do:
sz=get(0, 'CommandWindowSize');
command_line_width = sz(1);
Otherwise, you'll have to use a mex file:

if I create a plot with some tabs in the titles and try saving that to a local pdf file (via print function), I get some hashtags instead of tabs in the pdf. This does not occur in the visible figure.
For example, I plotted the residuals of an approximant to the runge function on a grid:
plot(g, f(g) - runge(g));
title(sprintf('residuals,\t max_x(s-f) = %.3f', max(f(g)-runge(g))));
Then after some axes manipulation (grid, boxes, etc..) I execute
h = gcf;
set(h,'Units','Inches');
pos = get(h,'Position');
set(h,'PaperPositionMode','Auto','PaperUnits','Inches','PaperSize',[pos(3), pos(4)])
print(h,'data/runge_example.pdf','-dpdf','-r200')
close(h)
Is somebody aware of that behaviour or better able to found that as already solved than I am?
EDIT: Same behaviour with saveas and saving to eps. This does not happen with \n
EDIT2: I'm using Matlab Version R2017b (9.3.0.7...)
So, after a long discussion we figured out that we have no idea of how to use tabs in matlab titles in combination with latex mode.
To clarify: use math environments and escape tex directives, otherwise it will throw an error.
so
sprintf('residuals,\t $max_x(\\vert s-f\\vert) = %.3f$', max(f(g)-runge(g))));
will give you a nice string:
residuals, $max_x(\vert s-f\vert) = 0.264$
The problem is, that it really is a tab. And the matlab latex interpreter (don't know which one that uses, the system or an own) crashes on that. I copy-pasted that to a tex document and pdflatex ran fine on it (but not showing that much space unfortunately).
So, I came up with the following fix:
use the latex directive \quad or \qquad:
title(sprintf('residuals,\\quad $max_x(\\vert s-f\\vert) = %.3f$', max(abs(f(g)-runge(g)))));
This will give you more space than a normal space.
EDIT: For this to work you need the interpreter of matlab to be set to "latex" instead of the default "tex". Do this by changing the title to
title(title_string, 'Interpreter', 'latex')
or by setting (globally for that script)
set(groot, 'defaultTextInterpreter', 'latex')
I want to use GUI (or directly the Command Windows) in MATLAB, which displays text. The text contain a few highlighted parts (which are changed during runtime), like this:
Is there any way I can do something liek that with MATLAB?
For command window you could try cprintf.
For displaying in a GUI you can use html formatting - going down this route you may find str2html useful.
I normally save my matlab figures as .eps and then make them better looking using Adobe Illustrator. This works for most figures but not all.
For example I plotted my data using the violin.m function from file exchange. When I save it as .eps and open it in Illustrator, I don't get an editable figure as I usually do. Instead, My figure appears chopped in horizontal sections, and all I can do is delete them (like in the figure below).
Is there anything I can do in either matlab or Illustrator to be able to edit the figure?
I don't need an .eps file, I just need to be able to edit it.
EDITS:
I tried #MattSchmatt's suggestion of using the print2eps function but I had the same problem.
Saving as .pdf doesn't solve the problem, because the image I get is not editable in Illustrator (plus, I also get the horizontal 'chunks').
A minimal, complete and verifiable example requires matlab, the violin function linked above and illustrator. But if it helps, here's the matlab code to produce a similar figure. I save by clicking on Figure -> save as. (But as I said above I tried the print2eps function and that was the same).
X = rand(100,6);
figure; violin(X)
I tried the following, didn't work either.
set(gcf, 'Renderer', 'painters')
As the author of the question suggests, I also wasn't able to export an editable (vectorized) .eps file into Illustrator. However, exporting it as .pdf does the trick. The 'fill' for the violin plots is weird, though, and has horizontal sections (perhaps something to do with the way the density estimate is being plotted?) all over. I was able to fix this and make the plots normal (with solid filled shades): select all the horizontal sections/chunks using the magic wand tool, and then increase opacity to 100% (it is set to 50 based on the exported file). Once all the required edits are made, export the file as .tiff and it seems to look fine. Hope this replicates, and thus helps! (my MATLAB version is 2016, and Illustrator version is the CS5)
I am trying to create a program in MATLAB by which I can click on an image (using the input command) and MATLAB outputs a graphic marker on the image, and stores the data to a text file.
The motivation for this comes the Major League Baseball Gameday App, as I want to use it for a similar purpose, but on the input rather than the receiving end. I have created a code which takes an image and outputs a graphic marker at the points clicked. However, I need to improve the code by (hopefully) color coding each marker according to a manual input (maybe using the reply function?) and also numbering each marker. Also, I would like it to output the reply, location, and number to a text file which can be saved for later.
The code I have is below (with comments explaining what is missing), any help is appreciated.
img=imread('Path/Filename.png');
image(img);
title('Pitching')
ginput
%ask for reply of text between each click
M=[ans];
N=length(M);
hold on
for i=1:N
plot(M(i,1),M(i,2),'o','MarkerFaceColor','r','MarkerSize',25);
%make FaceColor coded according to reply from click
%number each click
%write data to text file
end
I have made an program that can display many outputs in same textbox in matlab.
The main program do looping and the GUI catch the output and display the outputs in same textbox. But the problem is that the output is displayed in new line.
Iwan to display the output just in one line..
How to do it?
Here is my Gcode to display the output in the GUI.
letterr = ProcessOutput;
set(handles.text4,'String',letterr);
you can use
set(handles.text4,'String',strjoin(letterr));
depending on the version of matlab you are using, this function is implemented or not. If not, you can get it from here:
File-exchange: strjoin
