4-13 Logical function all(x) all(A) any(x) any(A) finite(A) Logical functions Table 4.3–4 Definition Returns a scalar, which is 1 if all the elements in the vector x are nonzero and 0 otherwise. Returns a row vector having the same number of columns as the matrix A and containing ones and zeros, depending on whether or not the corresponding column of A has all nonzero elements. Returns a scalar, which is 1 if any of the elements in the vector x is nonzero and 0 otherwise. Returns a row vector having the same number of columns as A and containing ones and zeros, depending on whether or not the corresponding column of the matrix A contains any nonzero elements. Returns an array of the same dimension as A with ones where the elements of A are finite and zeros elsewhere. Z.R.K (continued …)
Logical function ischar(A) isempty(A) isinf(A) isnan(A) Logical functions Table 4.3–4 (continued) Definition Returns a 1 if A is a character array and 0 therwise. Returns a 1 if A is an empty matrix and 0 otherwise. Returns an array of the same dimension as A, with ones where A has ‘inf’ and zeros elsewhere. Returns an array of the same dimension as A with ones where A has ‘NaN’ and zeros elsewhere. (‘NaN’ stands for “not a number,” which means an undefined result.) isnumeric(A) Returns a 1 if A is a numeric array and 0 otherwise. isreal(A) Returns a 1 if A has no elements with imaginary parts and 0 otherwise. logical(A) Converts the elements of the array A into logical values. xor(A,B) Returns an array the same dimension as A and B; the new array has ones where either A or B is nonzero, but not both, and zeros where A and B are either both nonzero or both zero. 4-14 Z.R.K
