Logical scalar values:
The MATLAB also has or and and operators which work element wise for the matrices:
These operators will compare any of the two vectors or matrices, as long as they are of similar size, element-by-element, and return a vector or matrix of similar size of logical 1's and 0's. The operators | | and && are only used with scalars, not matrices. For illustration,
>> v1 = [3 0 5 1];
>> v2 = [0 0 2 0];
>> v1 & v2
ans =
0 0 1 0
>> v1 | v2
1 0 1 1
>> v1 && v2
??? Operands to the || and && operators should be convertible to the logical scalar values.
As with numerical operators, it is significant to know that the operator precedence rules. Table shows the rules for the operators which have been covered faraway, in the order of the precedence.
Technique to creating this structure: An alternative technique of creating this structure, that is not as efficient, includes using the dot operator to refer to fields in the
ischar function: The ischar function return the logical true if an array is a character array, or logical false if not. >> vec = 'EK127'; >> ischar(vec) ans =
Related Structure Functions: There are many functions which can be used with structures in a MATLAB. The function isstruct will return 1 for logical true when the variable arg
