The wave traveled 100 meters at the speed of 340.29 meters per second If the variable speedofsound is equal, for instance, to 340.29, then the result would be: For example.įprintf(fid, 'The wave traveled %d meters at the speed of %f meters per second', 100, speedofsound) Adding number format sign at the place where the actual number should go will do this. Variable can be also printed inside the text.

There are some other escape characters which are described in MATLAB help. Fprintf command adds information to the opened file. "w" here means to open file with permission to write. Here is one of the ways to save data to file.įprintf(fid1, '# Minimum Energy GB Structure for LAMMPS\n') įprintf(fid1, '%f %f xlo xhi\n', xlo, xhi) įprintf(fid1, '%f %f ylo yhi\n', ylo, yhi) įprintf(fid1, '%f %f zlo zhi\n', zlo, zhi) įprintf(fid1, '%d 1 %f %f %f\n', ') įopen command simply opens the file for editing with fileID "fid1".

This tutorial does not show now to calculate or obtain this data but only how to write existing information in a different format. Now the objective is to save this information using LAMMPS standard formatting for future use. Tschopp InputĪssume that MATLAB have all the information and variables from MATLAB Import Data tutorial saved. This article will show how to use MATLAB command fprintf and some others to save data to the file.Īuthor(s): Dmitry I. The input saved variable is assumed to be to be similar to ones which obtained from using script and data file from MATLAB Import Data tutorial.

The objective of this tutorial is to demonstrate how to save MATLAB internal data to a file of defined formatting.
