openldr

 OPENLDR loads neuroscan LDR files
 LDR = OPENLDR(Filename [, PERMISSION [, Mode]]);
 LDR = OPENLDR(LDR [, PERMISSION [, Mode]]);

 LDR is a struct with the following fields
   LDR.FileName     Name of LDR-file
   LDR.Label_Out    Labels of output channels
   LDR.Label_In    Labels of input channels
   LDR.RR        re-referencing matrix
   LDR.datatype    'REREF_MATRIX' indicates this datatype

 PERMISSION    'r'    reads LDR file
         'w'    writes LDR file
         'r+w'    reads and writes LDR file 
            (useful in combination with RESCALE-Mode) 

 Mode [optional] 'RESCALE' performs a rescaling of the weights
        sum of positive weights becomes +1
        sum of negative weights becomes -1
