Converting a table that has all variables of the class char to string
I have a table t that contains a column year. The following command returns
class t.Year
ans =
char
This is not just for the column year but for all columns in the table.
I need to convert the table to a cellstr so that I can do str2num function on it. I am unable to convert all the columns and rows to string type. I also need to remove '' from the column names when I do table2cell. After table2cell I need to convert to cellstr and I am unable to do so since all the values in the table(columns) are char.

str2numacceptscharinput, it doesn't need to be a string. But you should be usingstr2doubleanyway.

Useclass(t.Year)to find its class.class blahwill always returncharsince that is equivalent to callingclass('blah').

thanks that helps. I found that class(t.Year) is double. I need to convert it to char. Is there anyway to do it in matlab? also I need to convert the whole table to a cellstr array.

str2num accepts char input, it doesn't need to be a string. But you should be using str2double anyway.– Cris Luengo

Use
class(t.Year) to find its class. class blah will always return char since that is equivalent to calling class('blah').– Navan
