TABLE_READ
Read an ASCII matrix data file.

TABLE_READ is a MATLAB program which can read an ASCII file defining a matrix of data.

The file may contain comment lines, which begin with a '#' in column 1. Otherwise, each line of the file contains all the entries of the next row of the matrix. Thus, in particular, every non-comment line must have exactly the same number of values.

Here is an example of the kind of file that TABLE_READ expects to process:

    # cvt_02_00010.txt
    # created by CVT_DATASET
    # at April 11 2003  12:04:56.303 PM
    #
    #  Spatial dimension M =   2
    #  Number of points N =  10
    #
    #  Initial SEED =    123456789
    #  Initialization by UNIFORM.
    #  Sampling by UNIFORM.
    #  Number of sample points =       500000
    #  Number of sampling iterations =    100
    #  L2 norm of datadataset change on last step =   0.001501

Usage:

x = table_read ( 'file_name' )

to define the array x to have the size and values of the array read from 'file_name'.
