Problem 105. How to find the position of an element in a vector without using the find function

May you please add this (or something similar) to the test suite:

% Test for find usage
fid = fopen(which('test'), 'r');
c = onCleanup(@()fclose(fid));
tline = fgetl(fid);
while ischar(tline),
if strfind(tline,'find'),
error('Don''t use find');
end
tline = fgetl(fid);
end

This should work fine after you've renamed your function.

there should be more test suite. such as x =[1 2 3;4 5 6;7 8 9];y =5;then the output is [2,2]; x = [1 2 2 3]; y =2;then the output is [2;2];

The test suite needs to be very restrictive here, the amount of trivial solutions is alarming. Yan
