matlab negation

In Matlab, you can negate a logical expression or a numeric array using the ~ operator. Here are a few examples:

1. Negating a logical expression:

a = true;
b = ~a; % b will be false

1. Negating a numeric array:

x = [1, 2, 3];
y = ~x; % y will be [0, 0, 0]

Please note that the ~ operator performs element-wise negation on numeric arrays. If you want to perform matrix negation, you can use the - operator. For example:

A = [1, 2; 3, 4];
B = -A; % B will be [-1, -2; -3, -4]

I hope this helps! Let me know if you have any further questions.
