I have a cell column vector of stock symbols that are all three letters long. I need to create a column vector of the same length that returns a 1 when the symbol XYZ is present, and 0 when it is not. I have wasted 2+ hours trying to figure this out, it is very frustrating.

For example, if I have this:

XYZ
DHU
EYU
XYZ
XYZ

then I need a column vector like this:

I appreciate the help. Have a great weekend.

在 MATLAB Online 中打开

Use strcmp like this:

>> A = {'XYZ';'DHU';'EYU';'XYZ';'XYZ'}
A = 
    'XYZ'
    'DHU'
    'EYU'
    'XYZ'
    'XYZ'
>> strcmp('XYZ',A)
ans =
     1
     0
     0
     1
     1
