# Convert matrix to Uitable

Asked by Light on 8 Jun 2013

A matrix is here

```U(35)=9;
```
```U(44)=29;
```
```A=[-1,1,1;0,-1,0;0,0,-1;1,0,0];
```
```blnA = logical( A == -1 );
```
```blnOut = find(any(A == -1,2));
```
```max(blnOut);
```
```negcolumn = find(A(max(blnOut),:) == -1);
```
```onerow = find(A(:,negcolumn) == 1);
```
```And i just wanna convert that matrix to uitable. Because i need a given row name and column name.
```
```f = figure('Position',[10 10 600 600]);
```
```dat = {-1,1,1;0,-1,0;0,0,-1;1,0,0};
```
```cnames = {'18','29','51'};
```
```rnames = {'12','26','35','44'};
```
```t = uitable('Parent',f,'Data',dat,'ColumnName',cnames,...
'RowName',rnames,'Position',[10 10 590 590]);
```
```max(blnOut)
```
```ans =
```
`       3`

My expected result is 35.

And will use that value 35 like that

```U(ans)=?
```
```U(35)
```
```ans =
9
```

If i solve it, My whole calculation will be perfect. Please give me your hand

Why give you a hand here rather than the thousand of other posts on this question that you've posted?

This will do it:

```U(35)=9;
U(44)=29;
A=[-1,1,1;0,-1,0;0,0,-1;1,0,0];
blnA = sum( A == -1, 2 )
lastRow = find(blnA, 1, 'last')
f = figure('Position',[10 10 600 600]);
dat = {-1,1,1;0,-1,0;0,0,-1;1,0,0}
% Get that number from U:
```

Though if you are going to do that, why not just use numeric column names and row names?

```columnHeaders = {18,29,51};
```theAnswer = rowHeaders{lastRow};
