A matrix reference is usually created with a call to BOOK_MATRIX, using the ROW function or by arithmetic between existing matrices.
If this argument is an expression which results in a matrix, then the member name should be specified.
This argument should be of type String.
If the member name is omitted, a default member name equal to the name of the global variable associated with the matrix, will be assigned to the histogram. This is in many cases a meaningful default and there is therefore rarely a need to specify a member.
This argument should be of type String.
