Hi
When importing data from Excel using xlsread() regadless if the data is numeric or char in the Excel file once loaded into Matlab its always treated as a char. I've used isnumeric() to test data type and this always fails to spot the data as a number.
The same code works with other files so suspec its the file but in Excel the formats are saved as General( as per the working files).

Is the data a char in the excel file?
You could always brute force it:
is_str_a_num = str2double(char_num); %is it a number?
if ~isnan(is_str_a_num); %?
num = is_str_a_num; %it is! woohoo
else
something_else; %it isn't
end
