Ran in:
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 4 44 84 124 164 5 55 105 155 205 6 66 126 186 246 7 77 147 217 287 8 88 168 248 328 9 99 189 279 369
t(:,2) = []
t = 9×4 table
t y z r _ ___ ___ ___ 1 21 31 41 2 42 62 82 3 63 93 123 4 84 124 164 5 105 155 205 6 126 186 246 7 147 217 287 8 168 248 328 9 189 279 369
% 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
t y r _ ___ ___ 1 21 41 2 42 82 3 63 123 4 84 164 5 105 205 6 126 246 7 147 287 8 168 328 9 189 369
