4 cze 2023 · The ! operator means whatever follows will be passed to the operating system (assuming it is the first part of the command, otherwise it is an error.) You cannot change that definition. The ~ operator means logical negation, and the ~= operator means not equals. a = ~true. a = logical.

Learn how to use relational operators such as == and ~= to compare arrays in MATLAB. Find out the difference between = and ==, and see other operators, symbols, and special characters in MATLAB.
14 kwi 2014 · This MATLAB function returns a logical array or a table of logical values with elements set to logical 1 (true) where inputs A and B are not equal; otherwise, the element is logical 0 (false).
5 paź 2010 · Why is .not..eq. represented by ~=? For the same reason that it is not represented as =!= or /= or any of the hundred and one other conventions used in programming languages. And the twiddle, or ~, is widely used in logic texts to mean NOT.
Calling ~= or ne for non-symbolic A and B invokes the MATLAB ® ne function. This function returns a logical array with elements set to logical 1 (true) where A is not equal to B; otherwise, it returns logical 0 (false). If both A and B are arrays, then these arrays must have the same dimensions.
21 lut 2017 · You want an error to return only if A is not in the set {'A','B'}. So a call to ismember might be a good alternative. Regardless, given the approach you have followed, if x is equal to 'A', then the second half of the clause will be true, even though the first part of the clause is false. And the logical statement.
27 gru 2023 · The ~= operator in MATLAB performs an inequality comparison between two values, vectors or matrices. According to MATLAB‘s documentation, ~= "Compares two arrays element-wise for inequality". For example, let‘s break down this simple comparison: 5 ~= 7. The code above checks if the scalar 5 does not equal 7.
