MATLAB: Wild cards for variable names

variable name

Hi,

i have a series of vectors whose name start with HCE. For example: HCEcool, HCElighting, HCEth.

I would like to add them up without going through the trouble of writing them all out. Is there a wild card that would allow me to do this?

Something like HCE* for example?

Thanks!

Meli

s=whos('HCE*')
out={s.name}

MATLAB: Simple wild card function for ismember?

No, there is no wildcard with ismember.

If your Timestamp_str is an array of characters all the same length, then

strcmp(cellstr(Timestamp_str(:,end-7:end)),'20:30:00')

If your Timestamp_str is a cell array of characters, then

cellfun(@(S) strcmp(S(end-7:end),'20:30:00'), Timestamp_str)

Alternately with regexp,

~cellfun(@isempty,regexp(Timestamp_str, '20:30:00$'))

If you just want the true/false of whether there was a match or not. The regexp itself will return the index of the trailing 23:30:00 in each string, with an empty cell for cell entries that do not match.
