MATLAB: Do anyone know how to merge several (80-90) csv file data into 1 file

Question

I have to merge data from several csv files into one csv file and find the maximum value of each column.

How shall I do it?

Answer 1

Assuming that all files have the same columns I'd do something like this:

• where ncols is number of columns
• preallocate max value variable: m = zeros(1, ncols);
• loop over all files
• read csv data using csvread into variable data
• m = max(max(data), m);
• end loop

m of course is your result.
