Answer 1

[Mathieu NOE]

maybe this ?

X = (1:9)'*(1:10:50);

% remove only 2nd column
t = array2table(X,'VariableNames',{'t' 'x' 'y' 'z' 'r'})

t = 9×5 table
    t    x      y      z      r 
    _    __    ___    ___    ___

    1    11     21     31     41
    2    22     42     62     82
    3    33     63     93    123

    9    99    189    279    369

t(:,2) = []

t = 9×4 table
    t     y      z      r 
    _    ___    ___    ___

    1     21     31     41
    2     42     62     82

% remove every 2nd column (c = 2,4,6,...)
t = array2table(X,'VariableNames',{'t' 'x' 'y' 'z' 'r'});
t(:,2:2:end) = []

t = 9×3 table
