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:
-
Withmatrix 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.
-
InThe others cases the result is the boolean %f
-
Withlist 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.
-
Withtlist and mlist object. If no overloading function is defined the list comparison method is used.
-
Withother 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
