Hello.

How can I find a word in a long vector of words, for example:

x={'shoemoney'
    'devices'
    'mcburnett'
    'gdri'
    'ezralevant'
    'Winston80'
    'daniellean'
    'geokem7'}
x = 8×1 cell array
    {'shoemoney' }
    {'devices'   }
    {'mcburnett' }
    {'gdri'      }
    {'ezralevant'}
    {'Winston80' }
    {'daniellean'}
    {'geokem7'   }

How do I find the locations of gdri?

Thanks in advance.

在 MATLAB Online 中打开

Try this:

wordList = {'shoemoney'
    'devices'
    'mcburnett'
    'gdri'
    'ezralevant'
    'Winston80'
    'daniellean'
    'geokem7'
    'abs gdri def'};
logIndexes = contains(wordList, 'gdri'); % Logical vector.
linearIndexes = find(logIndexes) % Convert to only the indexes that are 1 for the logical index value.
linearIndexes = 2×1
     4
     9
for k = 1 : length(linearIndexes)
    thisIndex = linearIndexes(k);
    fprintf('gdri shows up in item #%d : "%s"\n', thisIndex, wordList{thisIndex})
end
gdri shows up in item #4 : "gdri"
gdri shows up in item #9 : "abs gdri def"
