i have two edit texts,they show the vectors :
1 1 1 1 and 1 -1 1 1
-1 1 1 1 -1 1 1 -1
how can i add the two first lines together and the two secondes lines together and the result is :
2 0 2 2

Presumably you have two multiline edit text controls such that when you call
get(handles.edit1,'String')
a cell array is returned. We can probably simulate this with
text1Array = [cellstr('1 1 1 1') ; cellstr('-1 1 1 1')];
which returns a cell array with two elements where each element is a string. We can then want to convert each string into an array of numbers so that we can add the lines together. If we assume just two lines of four elements each then
arraySum1 = str2num(text1Array{1,:}) + str2num(text1Array{2,:});
which returns
arraySum1 =
0 2 2 2
which is the sum of the first two lines. You can then repeat this for the other edit text control.
text2Array = [cellstr('1 -1 1 1') ; cellstr('-1 1 1 -1')];
arraySum2 = str2num(text2Array{1,:}) + str2num(text2Array{2,:});
and concatenate the two and convert to a string as
concatenatedArraysAsString = num2str([arraySum1 arraySum2]);
where
concatenatedArraysAsString =
0 2 2 2 0 0 2 0
The answer is different from yours so perhaps I've misunderstood your rules.

Huh. Looks like you changed your question from when I started writing an answer for it....

Let A and B be your matrices.
iwant = A+B;
Best programmer please read basics of matlab.
