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

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) .....

Can you provide a sample: matrix, X?

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

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???
