I am facing a problem trying to read in a csv file of 200 rows by 4096 columns. I have tried the following commands to read in the file: csvread, xlsread, load However, each time I noticed that I was only able to read in 200 rows by 256 columns to a data array. When I did a preview of the csv file in Matlab, I saw the message 'Preview truncated at twenty thousand characters'. If the number of rows is only 100 rows, then the number of columns that I am able to read in is 2048. It seems that there is a limit to the number of data values that Matlab will be able to read in from a file. May I know if there is a way to extend the memory space of Matlab so that I can read in data values from a csv file with more than 200 rows by 4096 columns?
