Hi everyone,

the question is simple:

why can I do this

>> DATA(1:15,[1:4,13])
ans =
         0    0.1803    0.3203    0.7438    0.4269
0000    0.1897    0.3556    0.8024    0.3909
0001    0.1156    0.3319    0.6641    0.3755
0001    0.1996    0.3653    0.8183    0.3961
0002    0.0993    0.3325    0.6299    0.4166
0002    0.0767    0.3281    0.5458    0.4681
0002    0.0000    0.3000    0.3317    0.3806
0003   -0.0236    0.3770    0.3004    0.3652
0003   -0.0959    0.3123    0.2093    0.3652
0004    0.0359    0.4026    0.4127    0.3549
0004    0.1000    0.4768    0.6102    0.3034
0004    0.0792    0.4322    0.5611    0.4990
0005    0.1652    0.4498    0.6640    0.3240
0005    0.0736    0.3865    0.4678    0.3446
0005    0.1145    0.4484    0.5628    0.3549

in my command line, but when I do this (on the same data)

% Display in table
app.LoadedDataTable.Data = app.DATA(1:15,[1:4,13]);

I get an "index in position 1 exceedes array bounds" error? (The table is also set up to have 5 columns.)

The second is in an App environment where I'm simply trying to display the data in matrix DATA in a UiTable component.

Thanks.

TestTableInput.mlapp

Have you tried debugging the line

app.LoadedDataTable.Data = app.DATA(1:15,[1:4,13]);

I would check the size of app.DATA

I believe you may be exceeding the array bounds of app.DATA. Once you are in debug mode and trigger that line, type the command below in the command window which should show k>> in debug mode.

size(DATA)

I made a test app, but could not replicate your error (see attached).
