eq - Test for equality
Syntax
A == B
eq(A, B)
Description
A == B compares each element
of array A for equality with the corresponding
element of array B, and returns an array with elements
set to logical 1 (true) where A and B are equal, or logical 0 (false) where they are not equal. Each input of the expression can be an
array or a scalar value.
If both A and B are scalar
(i.e., 1-by-1 matrices), then the MATLAB software
returns a scalar value.
If both A and B are nonscalar
arrays, then these arrays must have the same dimensions, and MATLAB returns
an array of the same dimensions as A and B.
If one input is scalar and the other a nonscalar array, then
the scalar input is treated as if it were an array having the same
dimensions as the nonscalar input array. In other words, if input A is the number 100, and B is a 3-by-5
matrix, then A is treated as if it were a 3-by-5
matrix of elements, each set to 100. MATLAB returns an array
of the same dimensions as the nonscalar input array.
eq(A, B) is called for
the syntax A == B when either A or B is an object.
Examples
Create two 6-by-6 matrices, A and B, and locate those elements of A that
are equal to the corresponding elements of B:
A = magic(6);
B = repmat(magic(3), 2, 2);
