MATLAB: Equivalent of isfield for tables

isfieldtable

I'd like to know if my Matlab table has a particular column. If it was a structure I'd use isfield. Is there a built in function for this?

I would also like to suggest using ismember()

For instance:

f1 = 1; f2 = 10; t = table(f1,f2)
t = 
    f1    f2
    __    __
    1     10
ismember('f1', t.Properties.VariableNames)
  logical
   1

It also works for a range of values:

ismember({'f0','f1','f2'}, t.Properties.VariableNames)
  1×3 logical array
   0   1   1

Just figured this out: have to use array2table,

   T = array2table(rand(30,8), ...
      'VariableNames', {'var1' 'var2' 'var3' 'var4' 'var5' ...
      'var6' 'var7' 'var8'});

However if you want to assign other properties besides names, you have to do that separately, unlike the table command,

T.Properties.VariableUnits = {'kg' 'm' 'W' 's' 'g' 'kg' 'm' 'W'};

mask = ismember(YourTable.Properties.VariableNames, ListOfColumnsYouWant);
NewTable = YourTable(:,mask);
