Given an integer n, make an n-by-n matrix made up of alternating ones and zeros as shown below. The a(1,1) should be 1.
Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displa...
Given the input n, return true if n is odd or false if n is even.
