Generate a vector like 1,2,2,3,3,3,4,4,4,4 So if n = 3, then return [1 2 2 3 3 3] And if n = 5, then return [1 2 2...

Take as input an array of digits (e.g. x = [1 2 3]) and output an array of digits that is that number "incremented" properly, (i...

Given a vector of numbers, return true if one of the numbers is a square of one of the other numbers. Otherwise return false. E...

You are given two line segments. Do they cross? Consider one segment as (x1,y1) to (x2,y2), the other segment as (x3,y3) to (...

Triangle numbers are the sums of successive integers. So 6 is a triangle number because 6 = 1 + 2 + 3 which can be displa...

Given a number n, create an n-by-n matrix in which the integers from 1 to n^2 wind back and forth along the rows as shown in the...

Return a list of all values (sorted smallest to largest) that appear exactly three times in the input vector x. So if x = [1 2...

Write a function which returns every other element of the vector passed in. That is, it returns the all odd-numbered elements, s...

At one time or another, we all had to memorize boring times tables. 5 times 5 is 25. 5 times 6 is 30. 12 times 12 is way more th...

There will always be at least one prime in the matrix. Example: Input in = [ 8 3 5 9 ] Output out is 4...

In MATLAB, you create a vector by enclosing the elements in square brackets like so: x = [1 2 3 4] Commas are optional, s...

Return true if the elements of the input vector increase monotonically (i.e. each element is larger than the previous). Return f...

Remove the nth column from input matrix A and return the resulting matrix in output B. So if A = [1 2 3; 4 5 6]; and ...

Given the input n, return true if n is odd or false if n is even.
