Hello,

I want to load a file and then check if there are missing values of the type

-99.99.

E.g.:

load('D:\My Documents\My work\ART_Value effect\Data\CRSP\marketindex_mon.txt');
checkmiss(marketindex_mon)

For this I wrote the file checkmiss:

function checkmiss(dataset)
% checks for missing values in dataset
idx=find(dataset==-99.99);
if isempty(idx)
    fprintf('dataset has no missing values -99.99')
else
    fprintf('dataset has missing values -99.99')
end
return;

I want it to display not 'dataset has no missing values -99.99' but 'marketindex_mon has no missing value', that is to always write the name of the dataset in question. Do you know how to do it?

Thank you.
