Check if sorted.
Input x = [1 2 0]
Output y is 0
There will always be at least one prime in the matrix.
Input in = [ 8 3

Output out is 4...
Given a circular pizza with radius _z_ and thickness _a_, return the pizza's volume. [ _z_ is first input argument.]
Calculate the nth Fibonacci number.
Given n, return f where f = fib(n) and f(1) = 1, f(2) = 1, f(3) = 2, ...
Given a vector of numbers, return true if one of the numbers is a square of one of the other numbers. Otherwise return false.
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...
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.
Regardless of input, output the string 'yes'.
Flip the outermost columns of matrix A, so that the first column becomes the last and the last column becomes the first. All oth...

Return true if the elements of the input vector increase monotonically (i.e. each element is larger than the previous). Return f...
Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displa...
Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Remove the nth column from input matrix A and return the resulting matrix in output B.
A = [1 2 3; 4 5 6];
Write a function which returns every other element of the vector passed in. That is, it returns the all odd-numbered elements, s...
Given a and b, return the sum a+b in c.
Write a two-input, two-output function that swaps its two input arguments. For example:
[q,r] = swap(5,10)
returns q = ...
Given the input n, return true if n is odd or false if n is even.
Find the sum of all the numbers of the input vector x.
Input x = [1 2 3 5]
Output y is 11
Input x ...
In MATLAB, you create a vector by enclosing the elements in square brackets like so:
x = [1 2 3 4]
Commas are optional, s...
Try out this test problem first.
Given the variable x as your input, multiply it by two and put the result in y.
