'~' is used instead as a logical NOT operator. This means that "not equal to" will be represented by "~=" in MATLAB. I hope that clears your doubt.

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.
MATLAB ® represents Boolean data using the logical data type. This data type represents true and false states using the numbers 1 and 0, respectively. Certain MATLAB functions and operators return logical values to indicate fulfillment of a condition.
5 paź 2010 · The tilde character (~) is generally used as the bitwise NOT operator. As the ! character is reserved for an other usage (OS command), I guess it's not a bad choice.
Syntax. ~A. not(A) Description. ~A represents the logical NOT. ~A is true when A is false and false when A is true. example. not(A) is equivalent to ~A. Examples. collapse all. Set Assumption Using NOT. Create a logical condition by using ~. syms x y. cond = ~(x > y); Set the assumption represented by the condition using assume. assume(cond)
Comparison operators compare the value of two numbers, and they are used to build logical expressions. matlab reserves the symbols >, >=, <, <=, ~=, ==, to denote “greater than,” “greater than or equal,” “less than,” “less than or equal,” “not equal,” and “equal,” respectively.
17 lip 2022 · The boolean operators are & (boolean AND) | (boolean OR) and ~ (boolean NOT /negation). A value of zero means false, any non-zero value (usually 1) is considered true. Here's what they do:
