count string in a cell array
显示 更早的评论
How can I count how many times a pattern of a string /char is presented in a cell array ????
string = 945
cell = {1234, 9456, 9457 }
I want the result to be = 2

Are the contents of the cell array numeric (e.g. class "double"), string, or character array?
Similarly, is the variable you named "string" a numeric, a string, or a character array. (Calling a variable "string" or "cell" is a bad idea, because those are MATLAB keywords.)
If one of your cell elements was 9457945, would that count once, or twice, in the total?

cell = {1234, 9456, 9457 }
strong = 945
count = sum(contains(string(cell),string(strong)))

This solution is a good illustration of why "string" is a bad variable name.

>> S = '945';
>> C = {'1234', '9456', '9457'};
>> nnz(~cellfun(@isempty,strfind(C,S)))
ans = 2
