Hi,
I have matrix shown bellow:
I need to extract fields :
- fname
- bbpx-x1 , bbpx-y1, bbpx-x2,bbpx-y2 (combined in one row as [39 , 116, 569, 375].
So as a result I should get Output 8144*2 ;
'00001.jpg' [39 , 116, 569, 375]
'00002.jpg' [64 , 336, 159, 275]
... ....
'n.jpg' [n , n, n, n]
Thank you for your help!

Hi Vktor,
Try this below:
outPutCellArray = cell(numel(myStruct),2);
for i = 1:numel(myStruct)
outPutCellArray{i,1} = myStruct(i).fname;
outPutCellArray{i,2} = [myStruct(i).bbpx_x1,myStruct(i).bbpx_y1, myStruct(i).bbpx_x2, myStruct(i).bbpx_y2];
end

Btw, you are asking for a table but showing a dataset example in your variables window. These are also different things too.

Try this then,
outPutCellArray_new = cell(numel(myStruct),2);
for i = 1:numel(myStruct)
temp = [myStruct(i).bbpx_x1,myStruct(i).bbpx_y1, myStruct(i).bbpx_x2, myStruct(i).bbpx_y2];
outPutCellArray_new{i,1} = myStruct(i).fname;
outPutCellArray_new{i,2} = strrep(strrep(strrep(num2str(temp),' ',' '),' ',' '),' ',',');
end
C = cell2table(outPutCellArray_new);
