javaScript now has sufficient functionality to read matrices from an ascii data source. The script would look something like:

ds=new DataSource("\root\asciimatrix.txt")
ds.setConfiguration("dataStartLine","1")
ds.setConfiguration("readFieldNames","true")
ds.setConfiguration("readFieldNamesLine","0")
ds.reset()
m=new DataMatrix(ds, "[Matrix,50,0,0,0.5,0.5]")

NOTES:

You must use a DataMatrix, as a Matrix is simply a static matrix that is not connected to a data source.

The call to reset() is essential as it tells the data source to reparse the data file after the configuration settings have been changed.

The text identifying the matrix "[Matrix,50,0,0,0.5,0.5]" must match exactly with the text in the data file.
