How to remove double quotes from a field?

I have a structure dataMtb which contains a field genes. The field is a cell array having dimension of 4109*1 and contains double-quoted alphanumeric content in each cell. I need to remove the quotes from all the cells. (e.g. "Rv001c" ---> Rv001c). I am attaching the structure file for reference.

Answer 1

S = load('dataMtb.mat') ;
str = S.dataMtb ;
str.gene = cellfun(@char,str.gene,'un',0) ;

The double quotes indicate the data is cell array of "string" class, not cell array of "char" class. They are not part of the data value itself.

Not sure what is your real need to "remove" the double quotes, you might want to re-consider whether you want to convert the class of the data.

Thank you for the information Fangjun. I am new to MATLAB so I don't know much about it. I actually need to convert it to match it with another cell array of char class.
