Unsupported datatypes

These are as follows:

• Complex numbers.
• Custom numeric datatypes, for example, a variable that is double precision and an object.
• Signed or unsigned numeric integers for non-grouping data, for example, unint8 and int16.
• Sparse matrices, for example, matrix ONE such that issparse(ONE) returns 1. To use data that is of datatype sparse, recast the data to a matrix using full.
