I have a cell array of ca and I need to be able to remove an entire column. So far I am able to delete the last column 'Final', but not sure how to delete the middle columns since its a mixed cell array of char and doubles.

ca = {'Name','Test1','Test2','Test3','Final';
      'A', 70 , 80 , 100, 99;
      'B', 30 , 90, 95, 90;
      'C', 100, 70, 85, 90}
newCa = ca(:,2:end)

在 MATLAB Online 中打开

ca = {'Name','Test1','Test2','Test3','Final';
      'A', 70 , 80 , 100, 99;
      'B', 30 , 90, 95, 90;
      'C', 100, 70, 85, 90};
% delete the third column, say:
ca(:,3) = []
ca = 4×4 cell array
    {'Name'}    {'Test1'}    {'Test3'}    {'Final'}
    {'A'   }    {[   70]}    {[  100]}    {[   99]}
    {'B'   }    {[   30]}    {[   95]}    {[   90]}
    {'C'   }    {[  100]}    {[   85]}    {[   90]}
