Uitable and vpa

Hi, I have problem with my code: vpa works for "result", but I need show result in the uitable1, but for "res" command vpa doesn't work.

matrix=[A B;C D] 
a=simple(matrix\X); 
b=sym(a) 
result=vpa(b,4) 
f=size(result); 

 for i=1:f(1); 
 for j=1:f(2); 
 res(i,j)=cellstr(char(result(i,j))); 
 end 
 end 

 set(handles.uitable1,'Data',res);

Please help

Instead of char(result), use num2str() or sprintf()

doc num2str
doc sprintf

and for the comparison,

doc char

[john]

sprintf

Function is not defined for 'sym' inputs.

did you mean clm(i,j)=num2str(uplne_vsetko(i,j),'%10.3e')???

PS: all matrix are created as cell matrix, then are converted with A(i,j)=sym(UserData.matrixA{i,j});

and then is result=vpa(b,4) .....

[Sean de Wolski]

Can you provide a sample: matrix, X?

[john]

for pushbutton 1:

matrixX=cell(4,4);

for i=1:4

for j=1:4

maticaX{i,j}='0';

end

end

UserData.matrixX=matrixX;

for pushbutton 2:

vx=size(UserData.matrixX);

for i=1:vx(1);

for j=1:vx(2);

X(i,j)=sym(UserData.matrixX{i,j});

end

end

[john]

it's works....:)

New question:

in case

martixA=zeros(4,4)

UserData.matrixA(1,1)=sym(strcat('-',(get(handles.edit5,'string'))));.....................

if string is number like 4.884032 it is ok, but in case if string is like "alfa", it is error,,,,,why???
