add lines cell matlab

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
 0 2 2 0

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....

thank you,i just want to say that these vector belong to different edit texts,so the first vector in the first edit text should be added to the first vector in the second edit text and sum will be displayed in another edit text.do you have some solutions. thanks for advence

Let A and B be your matrices.

iwant = A+B;
