Data Table Lookup class, interpn() data container

Data Table Lookup class gives the user a way to store, manage, manipulate and plot data as would be used with MatLab interpn() lookups.

The Data Table Lookup class (DTL) gives the user a way to store, manage, manipulate and plot numerical data as would be used with the MatLab functions interp1() to interpn(). Data contained in a DTL object consist of the independent sample point arrays, the dependent matrix as well as associated names, unit's and comment's fields.

Class is compatible with my "Digitizer" and "Visual Data Editor" apps.

Class methods can among other things do:

• Resample independent data points
• Reorder independent dimensions (permute)
• Plot
• Display the objects numerical and textual content.
• Generate independent and dependent DTL data from raw test data.
• Extrapolate
• Smooth or filter
• Execute interpn() lookups
• Test object validity (ie is it internally consistent)
• Merge and concatenate
• Rearrange the functionality so that an independent term becomes the dependent term.

All methods (except plot) can work on N dimensional data sets.

The DTL download contains demonstration mfiles to show the user how to use the methods.

Each method's help information contains a short summary of the method's purpose, a more detailed explanation of the implementation or usage, details of inputs and outputs and some example calls to the method.

New users should refer to the included "Getting Started With DTLs.pdf" file.
