equal

equal — (=) affectation, comparison equal sign

Description

`-`	Equal sign is used to denote a value affectation to a variable.
`-`	`a == b` denotes equality comparison between expressions `a` and `b`:
`With`	matrix objects,
`If`	`a` and `b` are matrices with same types and identical dimensions, the comparison is performed element by element and the result is a matrix of booleans.
`If`	`a` and `b` are matrices with same types, but `a` or `b` is a 1 by 1 matrix the scalar is compared with each element of the matrix. The result is a matrix of booleans.
`In`	The others cases the result is the boolean `%f`
`With`	list objects,
`If`	`a` and `b` are lists with identical sizes, the comparison is performed element by element and and recursively. The result is a row vector of booleans.
`If`	`a` and `b` are lists with non equal sizes the result is the boolean `%f`.
`With`	tlist and mlist object. If no overloading function is defined the `list` comparison method is used.
`With`	other data types (functions, libraries,...) , the result is `%t` if the objects are identical and `%f` in the other case.

Comparison between different data types returns %f.
