  [1X4.1 [33X[0;0YRead and write matrix[133X[101X
  
  [1X4.1-1 4ti2Interface_Read_Matrix_From_File[101X
  
  [29X[2X4ti2Interface_Read_Matrix_From_File[102X( [3Xarg[103X ) [32X function
  [6XReturns:[106X  [33X[0;10Ya list of vectors[133X
  
  [33X[0;0YThe  argument must be a string, representing a filename of a matrix to read.
  Numbers  must  be seperated by whitespace, and the first two numbers must be
  the number of rows and columns. The function then returns the matrix as list
  of lists.[133X
  
  [1X4.1-2 4ti2Interface_Write_Matrix_To_File[101X
  
  [29X[2X4ti2Interface_Write_Matrix_To_File[102X( [3Xarg[103X ) [32X function
  [6XReturns:[106X  [33X[0;10Ynothing[133X
  
  [33X[0;0YFirst  argument  must  be  a matrix, i.e. a list of list of integers. Second
  argument  has  to  be a filename. The method stores the matrix in this file,
  seperated  by whitespace, line by line. The content of the file, if there is
  any, will be deleted.[133X
  
  [1X4.1-3 4ti2Interface_Cut_Vector[101X
  
  [29X[2X4ti2Interface_Cut_Vector[102X( [3Xvec[103X, [3Xd[103X ) [32X function
  [6XReturns:[106X  [33X[0;10Ya matrix[133X
  
  [33X[0;0YTakes the vector [3Xvec[103X and produces a matrix with [3Xd[103X columns out of the entries
  of the vector.[133X
