I would like to find the elements of a cell array that contain part of a specified string.
colorList = {'Red', 'Green', 'Blue', 'Purple'}; % List of values to match with
stringToCheck = 'Blue 23948723'; % String we are trying to match
I would like to return index=3 of colorList since that entry contains the stringToCheck text of 'Blue'. How can I do this?

>> find( ismember( colorList, strsplit( stringToCheck ) ) )
ans =
3
or
>> find( ismember( colorList, strsplit( stringToCheck, {'\s','\.',','} ...
, 'CollapseDelimiters',true, 'DelimiterType','RegularExpression' ) ) )
ans =
3
if the color name is followed by a period or comma, e.g. "Blue.". And what about upper and lower case, e.g "blue"? And "Bluetooth"?

If your MATLAB is R2016b or later version, you can use contains function, like:
idx = cellfun(@(x) contains(stringToCheck,x),colorList);
The answer is:
>> colorList(idx)
ans =
{'Blue'}
