MATLAB: write a function that retuns logical true of vector or matrics or scaler is empty

Write a function that retuns logical true of vector or matrics or scaler is empty %% P2: Check for an empty matrix % Write a function myIsEmpty which takes one input (scalar, vector, matrix, ...) % and returns logical true if the input is empty and false otherwise. % DO NOT USE MATLAB's isempty FUNCTION! % % Example: An input of [] should result in the output true. % An input of 1 should result in the output false. % An input of [1, 2] should result in the output false. % An input of [2 3; 4 5] should result in the output false. BEGIN_PRECOND END_PRECOND BEGIN_SOLUTION % Your solution goes here END SOLUTION

Answer 1

one way is to use numel(input) function which will return number of elements in input. If return value is zero, then given input is empty.

The code will be:

n = (uint32(numel(input)) == 0));

Otherway is to use size(A) function.
