Read_matrix

Function: read_matrix (<S>)

Function: read_matrix (<S>, <M>)

Function: read_matrix (<S>, <separator_flag>)

Function: read_matrix (<S>, <M>, <separator_flag>) read_matrix(<S>) reads the source <S> and returns its entire content as a matrix. The size of the matrix is inferred from the input data; each line of the file becomes one row of the matrix. If some lines have different lengths, read_matrix complains.

read_matrix(<S>, <M>) read the source <S> into the matrix <M>, until <M> is full or the source is exhausted. Input data are read into the matrix in row-major order; the input need not have the same number of rows and columns as <M>.

The source <S> may be a file name or a stream.

The recognized values of <separator_flag> are comma, pipe, semicolon, and space. If <separator_flag> is not specified, the file is assumed space-delimited.
