MATLAB digit precision
Oct 03rd, 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?

Internally, Matlab uses double precision for its data.
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:

Thaks Maks,

"MATLAB does its internal arithmetic in IEEE floating point precision using approximately 16 decimal digits, but the default display is only 5 decimal digits, so do not be too concerned about the digits actually displayed as MATLAB output...."
