Comparing subsequent string elements in cell array in MATLAB

Question

I have a cell array Data<1048536x1> of strings in MATLAB. I would like to compare adjacent string elements in the cell array. Is there a function in MATLAB? I tried using strcmp but it only works when you have two strings not for adjacent strings in a cell array. Any help much appreciated.

Answer 1

To compare every string against the next string, use

sameIdx = find(strcmp(Data(1:end-1),Data(2:end)));

With this, the string at any position of sameIdx is the same as the string at position sameIdx+1. Note that this way, you don't need to check for the same previous string.
