Essentially, I am trying to do (pseudo code):
T=table(data); % T contains many columns of doubles, date times, and is otherwise numeric.
m = T.field == condition; % Logical indexing based on some field
T=T(m); % implicit application of mask m to each column in T.
Of course, the last line isn't supported by Matlab and returns an error:
Subscripting a table using linear indexing (one subscript) or multidimensional indexing (three or more
subscripts) is not supported. Use a row subscript and a variable subscript.
Is there a way to essentially downsample an entire table based on a logical index mask? It is conceivable that table T has a large (100s) of columns, and manually indexing into each column could be too time consuming.

Hi, I tried your solution, but it didn't work..
for dp=1:length(DataPoint)
data(dp,:)=adeInfo;
end
I get this error:
Right hand side of an assignment into a table must be another table or a cell array.
adeInfo is not a table. it is as follows, as shown in MATLAB: "A singleton class"
