I have a Matlab table (the new 'Table' class), let's call it A:
A=table([1;2;3],{'A';'B';'C'})
As you can see, some of the columns are double, some are cell.
I'm trying to figure out which ones are cells.
For some reason, there is no A.Properties.class I can use, and I can't seem to call iscell on it.
What's the "Matlab" way of doing this? Do I have to loop through each column of the table to figure out its class?
One approach -
out = cellfun(@(x) iscell(getfield(A,x)),A.Properties.VariableNames)
Or, a better way would be to access the fields(variables) dynamically like so -
out = cellfun(@(x) iscell(A.(x)), A.Properties.VariableNames)
Sample runs:
Run #1 -
A=table([1;2;3],{4;5;6})
A =
Var1 Var2
____ ____
1 [4]
2 [5]
3 [6]
out =
0 1
Run #2 -
>> A=table([1;2;3],{'A';'B';'C'})
A =
Var1 Var2
____ ____
1 'A'
2 'B'
3 'C'
out =
0 1
Run #3 -
>> A=table([1;2;3],{4;5;6},{[99];'a';'b'},{'m';'n';'p'})
A =
Var1 Var2 Var3 Var4
____ ____ ____ ____
1 [4] [99] 'm'
2 [5] 'a' 'n'
3 [6] 'b' 'p'
>> out
out =
0 1 1 1
