Variables also saves the global status of the variable, so that if it is Save the data in Octave's text data format.Įxcept when using the Matlab binary data file format, saving global Match all lower and upper case alphabetic characters. If the firstĬharacter is ! or ^, match all characters except those Match the list of characters specified by list. The list of variables to save may include wildcard patterns containing This is equivalent to compressing the file with gzip outside Octave. Use the gzip algorithm to compress the file. You should use this format only if you know that all the Save the data in HDF5 format but only using single precision.

(HDF5 is a free, portable binary format developed by the NationalĬenter for Supercomputing Applications at the University of Illinois.) Save the data in the binary format written by Matlab version 4. Save the data in Matlab's v6 binary data format. Save the data in Matlab's v7 binary data format. Values to be saved can be represented in single precision. Save the data in Octave's binary data format but only using single Save the data in Octave's binary data format. ) must be specified as character strings. Then the options, file, and variable name arguments If save is invoked using the functional form Modify the output format override the format specified by Save command are listed in the following table. If no variable names are listed, Octave savesĪll the variables in the current scope. The special filename ‘-’ can be used to write the Once one or more variables have been saved to a file, they can beĬommand: save options file v1 v2.

Written by the save command can be controlled using the functionsĪs an example the following code creates a 3-by-3 matrix and saves it I have some influence over the format of the header records, so if (for example) it would be better that they were not comments but provided in some other way, then that can be done.The save and load commands allow data to be written to and The extracted data would then be plotted.įorgive me for not posting an awful failed attempt: I have never before used Matlab or Octave or anything like that, I thought it better to ask than spend two weeks trying to "fast learn" yet another tool. I believe that this would involve the use of textread to extract the data from the header records, and then dlmread to extract the CSV data into arrays (Time, currentPos, PosPid etc.) The remaining records after the comments are standard CSV records.
