The question is really unclear. Please show the input and the wanted output, otherwise we cannot guess what "convert cell array into character" means.

This question doesn't make any more sense than when you asked it last time (in a question you have since deleted.)

Give an example input and the corresponding output that you would like to have.

Wait, I might finally understand ?!

Is your original data a matrix of pixels, perhaps even already broken up in to individual arrays of pixels around a character, and each matrix of pixels represents a character, and your task is to recognize _which_ character it is?

If so, then there are about 6 or 7 decades of research on this topic, so you should go visit Google Scholar and pick out some scientific papers, read AND UNDERSTAND them, and make a decision about which one you are going to implement.
