Hi Singh,

It sounds a little bit confusing. So if I'm wrong (which I probably am) please give us further clue on what you exactly after.

To me it sounds like you need to shift the matrix to write! Which is a simple task! However I don't know what's gonna happen to the last column! I assume you wanna keep it in last+1 column!

Based on all these not true assumptions I made I guess you will be good with a horizontal concatenation.

newData = horzcat(zeros(size(data,1),1),data);

However I don't think you're after something so easy.

Please explain your problem

Good Luck!

Salaheddin Hosseinzadeh,i wish to full square matrix first column is all 0

 DG2 =

         0   20.2581   82.1517   86.5606   88.6312
         0         0   82.3752   67.9051   73.8848
         0         0         0   88.7142   65.5844
         0         0         0         0   28.1114

and next tym i delete the first column than it will be full square matrix

DG2 =

   20.2581   82.1517   86.5606   88.6312
         0   82.3752   67.9051   73.8848
         0         0   88.7142   65.5844
         0         0         0   28.1114

and after deletion first column from DG2 than first column treat as first column but i wish it is treat as second column because when i plot on the biograph than self connecting nodes are not allowed

 h = view(biograph(DG2,[],'ShowWeights','on'))
Warning: Self connecting nodes are not allowed, ignoring the diagonal of CM.

in biograph i have five node but it will show only 4 andi have 10 edges but it will show only 6 edge.

Dear Singh,

I'm afraid I have no idea what is a biograph!

Here is the MATLAB documentation on how to define biograph

Have a look it may help you to define your biograph completely before viewing it.
