convert dataset into logs

Hi
I have imported an Excel dataset of real-time GDP. Which is a dataset of numbers in a triangular format.
So I want to convert this dataset into logs of these numbers. Is there any fast way??
Many thanks

You need to load the dataset into the MATLAB workspace (use xlsread), then simply use the logarithm function of your choice on the entire dataset. Your options are: log (Napierian logarithms), log2 (base 2 logarithms), or log10 (base 10 logarithms). Then save to the file type of your choice. (I suggest a ‘.mat’ file,)
For example:
DataSet = randi(10, 5, 3)
LogDataSet = log10(DataSet)
