A < B A > B A <= B A >= B A == B A ~= B
The relational operators are
~=. Relational operators perform element-by-element
comparisons between two arrays. They return a
of the same size, with elements set to logical
where the relation is true, and elements set to logical
where it is not.
>= use only the real part of their operands
for the comparison. The operators
real and imaginary parts.
To test if two strings are equivalent, use
strcmp, which allows vectors of dissimilar
length to be compared.
For some toolboxes, the relational operators are overloaded,
that is, they perform differently in the context of that toolbox.
To see the toolboxes that overload a given operator, type
If one of the operands is a scalar and the other a matrix, the scalar expands to the size of the matrix. For example, the two pairs of statements
X = 5; X >= [1 2 3; 4 5 6; 7 8 10] X = 5*ones(3,3); X >= [1 2 3; 4 5 6; 7 8 10]
produce the same result:
ans = 1 1 1 1 1 0 0 0 0
