How can I compare the multiple strings?

35 ビュー (過去 30 日間)
I am unable to compare the multiple strings at once to produce the required output. I have tried the following code. Here I would like to compare the input string and print the result from statements.
function result = select(sports)
sports = {'hockey','tennis'};_
if strcmpi(sports,'hockey');x=1;end
if strcmpi(sports,'cricket');x=2;end
if strcmpi(sports,'football');x=3;end
if strcmpi(sports,'tennis');x=4;end
result
end

What is your actual goal? I presume sports={'hockey','tennis'} is actually meant to be the input to your function (instead of overwriting it). If so, what do you want the output to be?

Thanks for your response. Yes, the input is sports = {'hockey', 'tennis'} and I want the output as [1 4]. I am trying to assign the values to the multiple strings in a matrix form. I am able to do it for a single string, but I want to do it for multiple strings (but not all) at once.

Is this what you want (using ismember to find the index of the sport in the list of all the sports?
% Test script:
fprintf('Beginning to run %s.m ...\n', mfilename);
allSports = {'hockey','tennis', 'cricket', 'football', 'racing', 'golf', 'Cody'};
thisSport = 'Football';
result = select(thisSport, allSports)
fprintf('%s is sport #%d.\n', thisSport, result);
fprintf('Done running %s.m.\n', mfilename);
%======================================================
function result = select(thisSport, allSports)
thisSport = lower(thisSport);
allSports = lower(allSports);
[~, result] = ismember(thisSport, allSports)
end

It looks like the code below should work.
result = select(thisSport, allSports);
Sports(result,result)

Please attach the Sports table in a .mat file if you still need help
save('answers.mat', 'Sports');
By the way, select is a built-in function so you might want to call it something else, like SelectSport() instead.
