Determine if the elements of an input array are triangle numbers and return the result as an array with the same dimensions as the input.
Input = [ 1 2 3 ];
Output = [ 1 0 1 ];
Watch out! Martix size!
This works in Matlab but not here? It fails on Test 3, but when I use the same value of x and the same function in Matlab it works...
Your output y is a row vector (or scalar), but in 3'rd test it should be a column vector. Predefine y first with the same size as x.
