Search row with string to find column number

I have created a matrix with row 1 full of strings and 4 other rows with numbers. They are created in a handle class with the object Projekter.

So in the object Projekter row 1, the first value is blank, but the second value is 'Ole'. So I know that 'Ole' is in column 2. x is the name/string I want to search for, which in this case is 'Ole'.

As you see below it should search row 1 from column 2 untill the end and if i = 'Ole', it should bring me the value 2 because i should be equal 2.

How do I fix this so I can get the i value when the statement is correct?

A is just a controller if the function works, but at this point it doesn't.

function number(obj,x)

            A = [];
            for i = 2:size(obj.Projekter,2)
                if obj.Projekter(1,i)==x
                    A = A + 1;
                end
            end
            disp(A)
        end

Is obj.Projekter a cell array of strings? If so then

[tf, A] = ismember(x, obj.Projekter);

tf will be false for elements of x that do not occur in obj.Projector. "A" will be the indices in obj.Projekter where the matches were found.

obj.Projekter is a cell array of strings yes.

Matlab still makes an error when I enter your code. It doesn't recognise the tf. It also give the error:

Undefined function 'eq' for input arguments of type 'cell'.
