String representation of any data type

Generate string representations of all MATLAB data types and user-defined classes.

TOSTRING implements an often-requested feature that is not built into MATLAB: represent some data as a string.
Supported and tested data types (of any dimension):
- double
- single
- logical
- char
- (u)int[X]
- cell
- struct
- function_handle
- user-implemented classes
The default string representation is as verbose as possible, meaning that the contents of structure fields, cell array entries, etc. are represented in fully expanded form.
S = TOSTRING(A, 'disp') produces a string representation that is identical to what the command 'disp(A)' would produce.

S = TOSTRING(A, 'compact') or S = TOSTRING(A, N) (with N a positive integer) limits the number of digits displayed in numerical arrays to either 4 ('compact') or N. A warning is issued when applied to a non-numeric array. Note that this setting also affects how enumeration classes are displayed; when this option is used, only the currently selected enumeration value will be shown, rather than the complete class.
