Hi
I have a problem can you help me?
This is problem;
I have a matrix like below;
45 45 65 65 28 28
1 1 9 2 4 1
9 4 7 2 3 1
this is how i want to do;
45-45 65-65 28-28
1-1 9-2 4-1
9-4 7-2 3-1
So I want to merge both cells into one cell, how can I do it?
thanks advance

Maybe something like this?
M = [ ...
45 45 65 65 28 28
1 1 9 2 4 1
9 4 7 2 3 1
];
fprintf([repmat('%d-%d\t',1,size(M,2)/2) '\n'],M.')
45-45 65-65 28-28 1-1 9-2 4-1 9-4 7-2 3-1

This prints to the command window. Is that what you mean by "print to workspace"?
And what do you want the new matrix to be, for the matrix M given above?

Depends upon what you mean by "merge" here...if you want the numeric result, that's
D=-reshape(diff(reshape(M.',2,[])),size(M,2)/2,[]).';
on above sample M array gives
>> D =
0 0 0
0 7 3
5 5 2
>>
NB: The negation operation since diff is X(i+1)-X(i) and the result of the first reshape() to create the 2-row array places the originally even-numbered column as the second row so it's the opposite direction of the way in which you've defined the differences. One could flipud the transpose before diff instead, but simply taking the negative is probably quicker.
If you mean you want to keep the two values but show them in a cell array as a 2-vector, that's for mat2cell() but one presumes that's not the actual Q?
