Hello, I have an array (class='double)

T =
0000    1.0000    1.0000    1.3521    0.1780         0    1.3966   10.0000
0000    1.0000    2.0000    0.9910    0.1720         0    1.4454   10.0000
0000    1.0000    3.0000    1.1243    0.1800         0    1.4053   10.0000
0000    1.0000    4.0000    1.0776    0.1750         0    1.3999   10.0000
0000    1.0000    5.0000    1.0350    0.1770         0    1.3809   10.0000
0000    1.0000    6.0000    0.9700    0.1750         0    1.4079   10.0000
0000    1.0000    7.0000    0.9111    0.1730         0    1.4379   10.0000
0000    1.0000    8.0000    1.1395    0.5280         0    1.4052   10.0000
0000    1.0000    9.0000    1.0037    0.1750         0    1.3662   10.0000

I want to insert this into a UITable but have column 1,2 & 3 with no decimals.

So I have tred this

            T=app.Timings                 % My data
            class(T)                      % 'double'        
            C1=num2str(T(:,1),'%.0f');             
            C2=num2str(T(:,2),'%.0f');
            T(:,1)=C1(:,1)
            T(:,2)=C2(:,1)
            
            
            app.UITable2.Data=T;
            T2=app.UITable2;
            T2.ColumnFormat = {'char' 'char' 'char' 'bank' 'bank' 'bank' 'bank' 'bank'};
            %app.UITable2.DisplayData

But Im getting weird results

I found this works:

             C = num2cell(T)
             app.UITable2.Data=C;
             app.UITable2.ColumnFormat={'char','char','char','bank','bank','bank','bank','bank'};

Hello,

Issue in your code is on this line. You asked for the number with 0 decimals, replace 0 with how many decimals you want there to be and it should be working.

C1=num2str(T(:,1),'%.0f');
