Hi, I have edit text in GUI. If I write into edit text for example aplha, is possible to convert string into greek letter?

Try for example uitable('Data',num2cell(char(945:969).'))

Convert string into greek letters

john il 14 Giu 2012

Sorry, this doesn't work

Walter Roberson il 14 Giu 2012

Works fine for me on Ubuntu 10.04 (Linux) under MATLAB R2007a, R2008b, R2010b

john il 16 Giu 2012

Here is my code:

h=findobj(0,'Type','figure','Tag','figure1');

UserData=get(h,'UserData');

function pushbutton12_Callback(hObject, eventdata, handles)

uitable('Data',num2cell(char(945:969).'))

set(h,'UserData',UserData);

guidata(hObject, handles);

Result of this code-in uitable will appear 25 rows with symbol square.

I have Matlab 7.12.0.635 (R2011a), Windows XP and also Vista. I don't know, what is wrong. Do I have make some settings in uitable properties?

Walter Roberson il 16 Giu 2012

Please check your system Regional Settings and see if you are set to a particular Code Page for your character set; please also let us know what Language you are set to.

The codes 945 to 969 are the Unicode codes for the lower-case greek characters. If you are set to a particular code page, they might be in a different place or they might not be available at all.

john il 18 Giu 2012

I don't know change "Change system locale", because my program has to work without changing of any Regional and Language Options. And I'm not sure, that I have to make some changes, because this code works correctly

text(.5,.5,texlabel('alpha)).

But, this is only for the text, and I need it for the uitable. :(

Walter Roberson il 18 Giu 2012

Try this:

foo = uitable('Data', {'<HTML>1+α'})

john il 18 Giu 2012

foo = uitable('Data', {'<HTML>1+α'}) works,

but all informations ( columns and rows ) I have in matrix result. How can I change your code to my situation?

Walter Roberson il 18 Giu 2012

Let S be your cell array to convert, and let each element of S be in char() form (you need an additional step if they are in sym form)

T = regexprep(S, 'alpha', 'α');

T = regexprep(T, 'beta', 'β');

T = regexprep(T, 'gamma', 'γ')

....

T = regexprep(T, 'omega', 'ω');

then set the uitable Data property to be T .

john il 20 Giu 2012

1. how can I group together command <HTML> and T.

.

T = regexprep(result(4,1), 'alpha', 'α')

t = uitable('Parent',f,'Data',{'<HTML>&',T})???

2. I need also index...for example, alpha23....number 23 has to be smaller than greek letter aplha

Walter Roberson il 20 Giu 2012

t = uitable('Parent', f, 'Data', strcat('<HTML>',T) )

For subscript 23, use

23

For example,

reppat = '$1;$2/';

T = regexprep(S, '(alpha)(\d+)', reppat);

T = regexprep(T, '(beta)(\d+)', reppat);

T = regexprep(T, '(gamma)(\d+)', reppat);

and so on.

john il 21 Giu 2012

1. t = uitable('Parent', f, 'Data', strcat('<HTML>',T) ) works great.

2. reppat = '$1;$2/';

T = regexprep(S, '(alpha)(\d+)', reppat);

....result is alpha;3/. Not greek letter. It can happen, that there will be alpha2beta4, so base on code in point 2. , than 2beta4 will be smaller chars, but beta has to be also bigger char. So this code is not so good.

Walter Roberson il 21 Giu 2012

Sorry, reppat should be

reppat = '&$1;$2';

john il 21 Giu 2012

Do you know change you code? If I have for example Capacitor23, then Capacitor has big size of chars and 23 are smaller ? Do you knok do this?

john il 21 Giu 2012

And if I write only alpha, then code doesn't works, only with some number like alpha34

Walter Roberson il 21 Giu 2012

I think this should do it:

T = regexprep(S, '([A-Za-z]+)(\d+)', '$1$2');

T = regexprep(T, '(alpha|beta|gamma|delta|epsilon|zeta|eta|theta|iota|kappa|lambda|mu|nu|xi|omicron|pi|rho|sigma|tau|upsilon|phi|chi|psi|omega', '&$1;', 'preservecase');

This should also handle upper-case greek letters.

john il 21 Giu 2012

It not possible what did you do :).

I little changed your code, but big thanks again.

Walter Roberson il 21 Giu 2012

Ah, I missed the close bracket after omega .

john il 25 Giu 2012

those greek letters works corretly :T = regexprep(T, '(alpha|beta|gamma|delta|epsilon|zeta|eta|theta|iota|kappa|lambda|mu|nu|xi|pi|rho|sigma|tau|upsilon|phi|chi|psi|omega|Gamma|Delta|Theta|Lambda|Xi|Pi|Sigma|Upsilon|Phi|Psi|Omega|tau|equiv|otimes|cap|int|perp|ni|cong|oplus|cup|times|oslash|o|nabla)', '&$1;');

Other letters from http://www.clemson.edu/ces/crb/procedures/greek/mat_greek.htm doesn't work. For example, if I write varsigma, then I get &varsigma, not greek letter....where can be I problem?

Walter Roberson il 25 Giu 2012

varsigma is not an HTML character entity. HTML appears to call it sigmav . See http://www.w3.org/TR/WD-math-970515/table04.html

john il 25 Giu 2012

In code I use sigmav. What I should write into edit text for correct convert into greek letter? sigmav or varsigma? If I write sigmav, I get &sigmav. If I write varsigma, I get var and greek letter sigma. So, it is not good.

Is it perhaps sigmaf ? http://www.w3schools.com/tags/ref_symbols.asp

Hi, sigma and sigmaf are OK. But theta and thetasym not. If I write thetasym I get symbol theta + sym for this code

T = regexprep(T, '(Alpha|Beta|Gamma|Delta|Epsilon|Zeta|Eta|Theta|Iota|Kappa|Lambda|Mu|Nu|Xi|Omicron|Pi|Rho|Sigmaf|Sigma|Tau|Upsilon|Phi|Chi|Psi|Omega|alpha|beta|gamma|delta|epsilon|zeta|eta|theta|iota|kappa|lambda|mu|nu|xi|omicron|pi|rho|sigmaf|sigma|tau|upsilon|phi|chi|psi|omega|thetasym|upsih|piv)', '&$1;');

but for this code

T = regexprep(T, '(thetasym|piv)', '&$1;');

is OK, but I need code for all letters.

Hi,

could you help me please? This is me code:

 vd=size(UserData.info);
 for i= 0:vd(1)-4
 T = regexprep(cellstr(char(sym(UserData.matrix{4+i,1}))), '([A-Za-z]+)(\d+)', '$1<FONT SIZE=-1>$2</FONT>'); 
 T = regexprep(T, '(Alpha|Beta|Gamma|thetasym|piv|Delta|Epsilon|Zeta|Eta|Theta|Iota|Kappa|Lambda|Mu|Nu|Xi|Omicron|Pi|Rho|Sigmaf|Sigma|Tau|Upsilon|Phi|Chi|Psi|Omega|alpha|beta|gamma|delta|epsilon|zeta|eta|theta|iota|kappa|lambda|mu|nu|xi|omicron|pi|rho|sigmaf|sigma|tau|upsilon|phi|chi|psi|omega|upsih|lsquo|rsquo|sbquo|ldquo|rdquo|bdquo|dagger|Dagger|bull|hellip|permil|prime|Prime|lsaquo|rsaquo|oline|euro|trade|larr|uarr|rarr|darr|harr|crarr|loz|spades|clubs|hearts|diams|forall|part|exist|empty|nabla|isin|notin|ni|prod|sum|minus|lowast|radic|prop|infin|ang|and|or|cap|cup|int|sim|cong|asymp|ne|equiv|le|ge|sube|supe|sub|sup|nsub|oplus|otimes|perp|sdot)', '&$1;');
 result(4+i,1)=strcat('<HTML>',T);
 end;

Code makes: if I write for example U1U2, than all numbers are subscript. But I need phi2U2, than everything after "phi" must be subscript, so 2U2 must by subscript.

Thank you

john il 23 Apr 2013

Hi, how can I insert sqrt into uitable? for example sqrt(2).

Surd doesn't help.

Thank you
