MATLAB: How to display 729 ‘double’ input arguments in tabular form? to get 729*729 matrix

doublematrix

I have a list of 729 elements, each element being 6-tuple. I want to display this list in the form of a table. Elements in rows is same as elements in columns.

H = cellstr( strcat('T', char('0' + fullfact([3 3 3 3 3 3])-1 ) ) );
emptyvals = repmat({''}, length(H), length(H));
YourTable = cell2table(emptyvals, 'VariableNames', H, 'RowNames', H);

Now YourTable is a 729 x 729 table in which each entry is an empty character vector (that you can then overwrite with appropriate content.) The columns are labeled, with

T000000    T100000    T200000    T010000    T110000 etc

and so are the rows.

In MATLAB, the column names for table() objects must be valid variable names so it is not possible to use pure numbers, but you could change the T to any alphabetic letter you wanted.

As discussed in https://www.mathworks.com/matlabcentral/answers/359051-how-to-display-729-double-input-arguments-in-tabular-form-to-get-729-729-matrix#comment_489118 it is important information that you are using R2013a and that you do have access to the Statistics toolbox. I asked you there whether you needed this for display purposes or only for computation purposes, and I showed you there how best to do this for computation purposes.

For display purposes, you will need a display that is a minimum of 36450 pixels wide, assuming that you are willing to accept 8 pixels per character including intra-character gap (narrower characters are hard to read; 6 pixels per character is considered barely readable.) This calculation assumes a 2 pixel gap between labels, which is quite tight.

To draw this, you would text() every character into place, having set the FontSize property to be quite small, and having set a monospaced font. To avoid having space take up a full character position, you would have to text() every column individually, but at least you can do an entire column at a time instead of having to do each item individually.

If someone is imposing on you a need to use a datastructure that looks sort of like this when it displays, then in R2007a to R2013a with Statistics Toolbox, you would use

H = cellstr( strcat('T', char('0' + fullfact([3 3 3 3 3 3])-1 ) ) );
emptyvals = repmat({''}, length(H), length(H));
YourTable = cell2dataset(emptyvals, 'ReadVarNames', false, 'ReadObsNames', false, 'VarNames', H, 'ObsNames', H);

MATLAB: Overloading arithmetic on graphs or digraphs

I'm afraid methods for MATLAB's digraph class can't be overloaded. There is still a way to get what you want, but it may be more work than it's worth:

You could write a new class, quantumGraph for example, that would contain a digraph class as a property. You would then overload the operators for this class (see how here).

However, you would also have to overload all methods of digraph that you are currently using for quantumGraph, to pass the data along to the digraph property inside the quantumGraph class.

This is a lot of work! The easier variant would be to just write functions quantumGraphSum, quantumGraphTimes, and so on, which would, for example, take a digraph and a scalar, and return a new digraph with modified properties.
