Hi, I have an array of doubles a. It has integers from 0 to 6. I want to keep the 0s and 2s, but change all other numbers to be 1. So I use a(~isequal(a,2) && ~isequal(a,0)) = 1; No error messages but the content a is still the same. Why? Thanks!
The isequal() function returns either a logical 0 or 1 depending on if the two arguments are equal. It does not return an element-by-element comparison. To do the element-by-element operation, use the == operator instead. Also use the element-by-element operator & instead of the logical operator &&. E.g.,
