You can utilize the "builtin" function to call the MATLAB built-in "xlswrite" from your overloaded "xlswrite" function. Your "xlswrite" will probably have a format as below:
function [success,theMessage]=xlswrite(file,data,sheet,range) % same structure as built-in "xlswrite"
% do the pre-processing
data = ...;
% call the MATLAB built-in "xlsread"
builtin('xlswrite', file, data, sheet, range);
end
Following is the documentation link for the "builtin" function that you can refer to:
Using this function will result in warning messages, since you are shadowing the MATLAB built-in "xlswrite" function. If you want to turn the warning messages off, you can execute the following commands at the MATLAB Command Window:
warning('off','MATLAB:dispatcher:nameConflict');
On the other hand, to turn the warnings on execute:
warning('on','MATLAB:dispatcher:nameConflict');
