MATLAB digit precision
Oct 03^rd, 2012, 5:39am

Greetings
I have been trying to import simulation data from Cadence into MATLAB. I save the simulation data in csv format and imported it into MATLAB, but the import wizard shows truncated values with only 4 digit precision while the original values taken from Cadence have upto 15 digit precision. I have attached a figure for reference. Can i enhance digit precision in MATLAB in import wizard?

By default, it displays only 5 digits. You can increase the number of displayed digits using "format long e" command. Check this link, or make a search on "Matlab precision" in Google: http://homepages.math.uic.edu/~hanson/MATLAB/MATLABformat.html
