Comparision of data names

Hi, I want to read images into the workspace and compare the image names with the image names stored in a cell array. My aim is to get the row from the cell aray where the image names are identical. The cell array contains data from an excelsheet (first column = name of image, second-fifth columns = values). With the code below I only get the name of the first image in dir. How do I get the position of the second, third,..image (stored in dir) from the cell array? Thanks in advance.

My code:

files = dir('*.tiff');
a=files.name
t={a}
[rn,cn]=find(strcmp(CellArray,t))

 t = {files.name};
 [Lia, Locb] = ismember(CellArray, t);

Or perhaps:

 [Lia, Locb] = ismember(CellArray(:, 1), t);

Maybe:

[Common, Index] = intersect(CellArray(:, 1), t);
