I doubt that you create your matrice like this. First of all this isnt even MATLAB syntax and second matrices cant store different types. To store different types you have to take cell arrays: A = {1.0, 'normal'}; Also: are normal and smurf variables or strings?

Solution 1

Given that you are talking about cell arrays and you want to search for a string you can use the function strcmp()[^].

Example:

A = {1.0, 1.0, 'abc' ,3; 2.0, 3.0, 'fff', 'abc'}

A = 

    [1]    [1]    'abc'    [  3]
    [2]    [3]    'fff'    'abc'

[rows, cols] = find(strcmp('abc', A))

rows =

     1
     2


cols =

     3
     4

Its easy ... you just have to look for the rows that contain a 1 after. See my updated solution for one way to do this. Also consider learning the Matlab Basics before starting to work with it.
