Scilab Function
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
.
Examples
a=sin(3.2)
[u,s]=schur(rand(3,3))
[1:10]==4
1~=2
