java.lang.Object

ca.nengo.io.MatlabExporter

public class MatlabExporter
extends java.lang.Object

A tool for exporting data to Matlab .mat files. Use like this:

MatlabExport me = new MatlabExport();
me.add("series1", series1);
...
me.add("series1", series1);
me.write(new File("c:\\foo.mat"));

MatlabExporter

public MatlabExporter()

Export data to Matlab .mat files

Method Detail

add

public void add(java.lang.String name,
       TimeSeries data)

Parameters:

name - Matlab variable name

data - Data to be stored in Matlab variable

add

public void add(java.lang.String name,
       TimeSeries data,
       float tau)

Filters TimeSeries data with given time constant (this is usually a good idea for spike output, which is a sum of impulses). TODO: this filter is prohibitively slow for large datasets

Parameters:

name - Matlab variable name

data - Data to be stored in Matlab variable

tau - Time constant of filter to apply to data

add

public void add(java.lang.String name,
       SpikePattern pattern)

Parameters:

name - Matlab variable name

pattern - Spike times for a group of neurons

add

public void add(java.lang.String name,
       float[][] data)

Parameters:

name - Matlab variable name

data - A matrix

makeVariableNameValid

public static java.lang.String makeVariableNameValid(java.lang.String name)

Parameters:

name - original possibly invalid name

Returns:

valid name that Matlab can use

removeAll

public void removeAll()

Clears all variables

write

public void write(java.io.File destination)
           throws java.io.IOException

Writes to given destination the data that have been added to this exporter.

Parameters:

destination - File to which data are to be written (should have extension .mat)

Throws:

java.io.IOException - if there's a problem writing to disk
