MATLAB: Find a string element in a structure matrix

findstringsstructure

assume i have a matrix t =

    'abc'
    'defg'
    'hi'
i want to check if 'abc' is in the matrix t

however this code doesnt seem to work

if (find(t == 'abc') >0)

i get the following error message Undefined function or method 'eq' for input arguments of type 'cell'.

The shown data cannot be a matrix, because a matrix must have a rectangular shape. I assume you mean a cell string:

C = {'abc', 'defg', 'hi'};

Then:

if any(strcmp(C, 'abc'))
  disp('abc found');
end

What does "here is my string" exactly mean? Strings do not contain the surrounding quotes. They appear only, if e.g. a cell string is printed to the command window:

C = {'string'};
disp(C)

Therefore I assume this is enough:

S = 'abc "abc" ';
S = strrep(S, '"', char(39));
fprintf('%s\n', S);

I use char(39) because it looks less strange than '''', but both create exactly the same: one quote character.

MATLAB: Find a string cell into a variable of a table

A(1,1) and B(:,1) return tables but strcmp is designed to accept character vector | character array | cell array of character vectors | string array.

To access the cell-strings, you need to use curly brackets!

A = table({'a'});
B = table({'a';'n';'n';'a'});
strcmp(A{1,1}, B{:,1})
ans = 4x1 logical array
   1
   0
   0
   1
