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

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???
