Calling options for function handles using cellfun

2 views (last 30 days)
I am confused about how to include options from built-in functions in a cellfun command. When I attempt either of the following commands:
X_member = cellfun('ismember',AllCoordinates, X, 'rows', 'UniformOutput', false)
or
X_member = cellfun(@ismember,AllCoordinates, X, 'rows', 'UniformOutput', false)
I get this error message: Error using cellfun Too many inputs.
I want 'ismember' to operate across rows in the matrices in each cell that I have. AllCoordinates is a 20x1 cell each containing 70000x3 matrices. X is a 20x1 cell containing matrices of different row numbers, but all have 3 columns. Does anybody know how to properly structure that command? Thanks in advance!

In order to use ismember with the 'rows' option, you need to build this into the function handle, not cellfun().
Something like:
cellfun(@(c,x)ismember(c,x,'rows'),AllCoordinates,X,'uni',false);

Thanks! Is there no other way to include function options when using cellfun? I know this method of calling cellfun is the slowest of all three unfortunately (when calling a function like ismember without using any additional options).
